    Field of the Invention
    [0001] The present invention relates to a bedding arrangement that has areas with firmness and / or height that are independently and automatically adjustable. Background of the Invention
    [0002] In a bed arrangement, a support is provided to act under the weight or part of a user's weight, where the bed distributes the user's body weight over a part of a device surface. Depending on how the bed distributes the user's weight, it will appear soft or firm. The level of firmness of such a bed is dependent on the properties of the elastic elements, such as the spring constant, and on how the elastic members were mounted on the bed, such as the level of fixation and pre-tensioning. In this way, the firmness of the bed is normally defined during the manufacture of the device.
    [0003] However, different people want and need different levels of firmness. In addition, different parts of the body may need different levels of firmness.
    [0004] It is known to provide bed arrangements with variable firmness. The induction of the elastic members to a deformation at different levels allows the firmness of the device to be adjustable. The deformation member has the ability to deform the elastic member regardless of the deformation to which the elastic member was induced. This means that the firmness of the bed can be adjusted during startup, according to the user's wishes. It is also possible to compensate for the firmness of the device with possible changes in the elastic properties of the elastic arrangement over time. In addition, it is common to vary the firmness independently in several zones / sections of a mattress.
    [0005] Such known solutions are described, for example, naEP 2 245 967 and WO 2009/120270. These two documents also describe the possibility of detecting the pressure being applied to the different zones and automatically controlling the firmness of the different zones, in order to decrease the total pressure.
    [0006] However, the definition of the most comfortable firmness for the various zones varies significantly from user to user. Thus, for several users, an overall minimization of pressure will not provide the most comfortable setting. In addition, the pressure distribution being applied to a mattress varies significantly depending on the type of lying position the user is in, and often a user will need the two different distributions of firmness between the zones and a level different firmness / overall softness of the mattress in different lying positions.
    [0007] Therefore, there is still a need for a bedding that can automatically adjust the firmness in order to provide a more comfortable bed, and thereby provide a more relaxing and healthy rest and sleep in a relatively economical way. Summary of the Invention
    [0008] Therefore, it is an objective of the present invention to overcome at least partially these problems and to provide an improved bedding.
    [0009] These and other objectives that will be apparent from the description below are achieved by a bedding and a method for controlling such a bedding, in accordance with the attached claims.
    [0010] According to a first aspect of the invention, a bedding is provided which has adaptable properties and which comprises: a mattress comprising at least one area which has independently adjustable firmness and / or height; a drive unit arranged to adjust the firmness and / or height of at least one said area; at least one sensor, said sensor (s) being adapted to measure a physical parameter, which may be related to a lying position used by a user; and a control unit arranged to determine, based on the record of said sensor (s), the current lying position of a user, said lying position can be determined to be an option among a series of hair minus two predefined lying positions, and to control the drive unit and adjust the firmness and / or height of said zone (s) to predefine the firmness / height values that correspond to the determined lying position.
    [0011] The experience of sleeping and what is considered comfortable or not, varies substantially from person to person. In addition, a user may often find it more comfortable to have a softer mattress when he is in a lying position, such as with his belly turned upwards, that is, in a leaning position, or on his side, than when he rests in other positions , such as on the back, that is, in the supine position. The present invention provides an efficient, however, relatively simple and economical way of varying the properties of the mattress depending on the user's choice of lying position, thereby providing in all cases the best possible comfort. This has been found to significantly improve the experience of sleeping and resting, which provides a better quality of rest and sleep. Improved sleep and rest also increase the user's health, and above all. It leads to a better quality of life.
    [0012] Preferably, at least one sensor is arranged in each of the zones. However, depending, for example, on the type of sensor used, it is also possible to determine a lying position through the sensors arranged only in one or a few zones, or through the sensors arranged outside the zones, for example, in a terminal section of the bedding.
    [0013] The mattress preferably comprises at least two zones that have firmness and / or independently adjustable height. However, even more preferably, it comprises at least three zones, and preferably at least five zones. For example, different zones with varying firmness can be provided at least for the user's hip area and shoulder area. Such zones can also be provided the foot area and the user's head area. Between these zones, zones with constant firmness / height can be provided. However, alternatively these zones can also have a variable firmness and / or height. Thus, in more refined modalities, 7, 10 or even more zones with variable firmness / height can be provided.
    [0014] Preferably, the areas that have firmness and / or independently adjustable height extend over essentially the entire width of the mattress and the areas that are separated in a longitudinal direction of the mattress. Since the same firmness is generally required, regardless of whether the user lies in the center or towards the sides, there is generally no need to separate the zones in the wide direction. However, in the case where the bedding must be used by more than one person at the same time, or if there is a need to distinguish between different lateral positions for other reasons, areas that have variable firmness / height and which also are separated in the wide direction.
    [0015] The series of predefined lying positions preferably comprises at least two, and more preferably three lying positions, which correspond to the user who lies on his back (supine position), with his belly turned upwards (leaning position) and on his side. However, more than three lying positions can also be defined. For example, different lateral lying positions can be defined, such as lying with the body straight or bent / bent forward or backward.
    [0016] The sensor (s) for determining the lying position can be of various types, and are arranged to determine various physical parameters related to the lying position. For example, the sensor (s) can be arranged to determine the weight that the user exerts on the mattress in various measurement areas, by measuring the deformation caused by the user on the mattress, by measuring the relative humidity of the air. in different positions, measuring the local temperature in different positions, or similar. The lying position can also be determined through automated visual inspection, using a camera, an IR sensor or similar.
    [0017] The sensors are preferably organized as a set of sensors that is arranged on the surface of the mattress. For example, the sensors can be arranged preferably flexible and the flat sensor wrap can be arranged on top of the mattress. The sensor envelope may have a characteristic of electrical impedance and, in particular, resistance, which varies with a normal force exerted on it. In particular, the sensor wrap can include an electrically conductive upper and flexible plate that comprises an upper conductive sensor, an electrically conductive flexible and lower plate that comprises a lower conductive sensor, and a flexible intermediate layer, such as a piezoresistive layer that has a region with an active sensor, which has an electrical impedance characteristic that varies according to a normal force exerted on it, said intermediate layer being located between said upper and lower conductive plates. The upper and lower plates are, in this case, conductively coupled to the intermediate layer. The sensors may preferably have characteristics of non-bilateral current versus voltage impedance. The piezoresistive layer can be created, for example, as electrically conductive particles suspended in a polymer matrix. The electrically conductive particles can be provided, for example, with a coating that includes at least one metal oxide, such as copper oxide, to thereby form with said layer a PN semiconductor junction. The wrap is preferably made, at least partially, of an elasticly stretchable material, and preferably, of a stretchable fabric. Examples of such sensor wraps that can be used in the bedding discussed above are those described in US 8 161 826 and WO 2009/120270, both said documents being incorporated herein by reference.
    [0018] The different lying positions and / or the different levels of firmness / height of the variable zones can be predefined or be defined and configured once and for all during manufacture, or during an initialization carried out, for example, by the seller. However, preferably at least a series of lying positions and the parameters of firmness / height can be defined by the user, and it is also possible that they will be reset and restarted over time.
    [0019] For this purpose, the control unit is preferably operable in a parameter setting mode, in which the predefined firmness / height values for the different zones in the different lying positions can be defined and / or adjustable. It is also preferable that, in parameter setting mode, the series of predefined lying positions can be defined and / or redefined.
    [0020] Through this, the user can register the parameter definition mode whenever he wants and in the parameter definition mode and he can adjust the firmness / height values for different zones and different lying positions, he can define new ones lying positions, or cancel previously defined lying positions. This can be done, for example, by the user who lies in bed and who assumes any lying position. The user can then adjust the firmness / height manually in the different zones until a comfortable definition has been obtained. The lying position and the firmness / height values for the different zones can then be stored. This can be repeated for the other lying positions. Alternatively or additionally, a previously stored lying position can be retrieved, and the firmness / height of the different zones can be adjusted and then stored.
    [0021] For communication with the control unit, a remote control can be used, which is adapted to communicate with the control unit, for example, via a wireless interface.
    [0022] The control unit can also be arranged to store, when the series of lying positions is defined or reset, the sensor data from the sensors that correspond to the predefined lying positions, and to use the stored data to distinguish between positions predefined lying when in an operating mode. It was discovered through the present invention that the data measured from a series of different sensors can be used to identify only a large number of different lying positions, using the magnitude of the individual measured values, and / or considering the (s) relationship (s) between the measured values at the same time. This can be used to predefine how different lying positions should be identified in general, regardless of the specific user. However, since the user with considerably different weight, height and body shape can use the bedding, it is preferable to define these values and / or ratio (s) individually for each user.
    [0023] The control unit can be arranged to determine, based on the registration of said sensors, the current lying position of a user in a continuous or regular manner. For example, the control unit can continuously monitor the sensor data and assess whether a change of lying position has occurred, or it can make such an assessment regularly, such as every 15 or 30 seconds, every minute, or similar . However, in an alternative or additional way, the control unit can be adapted to determine, based on the registration of said sensors, the current lying position of a user when it is determined that a sensor registration of any of the sensors is changed in comparison to a last value stored in the sensor from said sensor by a magnitude that exceeds a predefined limit value.
    [0024] The mattress can be of several types, such as one that comprises inflatable elements, elements with resilient foam, resilient rubber, elements filled with water, and the like. However, preferably the mattress comprises a plurality of spiral springs, and preferably spiral springs arranged in separate pockets of a cover material to define a spring mattress in pockets.
    [0025] According to another aspect of the invention, a method is provided for automatically adapting the properties of a bedding comprising the steps: providing a mattress comprising at least one area that has firmness and / or independently adjustable height ; provide at least one sensor, said sensor (s) being adapted to measure a physical parameter, related to a lying position used by a user; determine, based on the record of said sensor (s), the current lying position of the user, said lying position can be determined to be an option among a series of at least two predefined lying positions; and adjusting the firmness and / or height of at least one said zone to predefine the firmness / height values that correspond to the determined lying position.
    [0026] Through these additional aspects of the invention, similar objectives and advantages as discussed above in relation to the first aspect of the invention can be obtained. Brief Description of Drawings

Detailed Description
    [0029] A bedding according to a first embodiment of the invention is shown schematically in Figure 1. The bedding has adaptable properties, and more specifically it comprises at least one, and preferably at least two areas that have firmness and / or independently adjustable height.
    [0030] The bed arrangement 1 comprises a mattress 2 having a plurality of zones 21. In addition, the arrangement of sensor 3 is provided, which has at least one sensor 31 arranged in each of the zones. The sensors are adapted to measure a physical parameter which is proportional to the weight exerted by the user on the mattress in the measurement areas of the sensors. In addition, at least one drive unit 4 is provided which is arranged to adjust the firmness and / or height of the zones . A control unit 5 is arranged to receive registration from the sensors and determine, based on this registration, the current lying position of a user. The lying position is determined to be an option among a series of at least two predefined lying positions. In addition, the control unit 5 is arranged to control the drive unit (s) to adjust the firmness and / or height zones and preset firmness / height values that correspond to the determined lying position.
    [0031] The mattress comprises at least two areas that have firmness and / or independently adjustable height. However, it preferably comprises at least three of these zones, and preferably at least five zones. For example, different zones with varying firmness / height can be provided at least for the user's buttocks and shoulders. Such zones can also be provided for the user's feet and head. Between these zones, zones with constant firmness / height can be provided. However, alternatively, these zones can also have a variable firmness and / or height. In this way, in more refined modalities, 7, 10 or even more zones with variable firmness / height can be provided.
    [0032] In Figure 2a, an exemplary modality that has five zones with firmness and / or variable height is illustrated. The zones can, in this case, correspond to the head / neck, shoulders, pelvis, legs and feet (from one side to the other).
    [0033] In Figure 2b, an exemplary modality that has seven zones with firmness and / or variable height is illustrated. The zones may, in this case, correspond to the head / neck, upper shoulder / back, lumbar, buttocks / pelvis, thigh / knee, calf / lower leg and foot / ankle (from side to side).
    [0034] In Figure 2c, the same areas of Figure 2b are provided, but in this case, only the shoulder / upper back zone and the buttocks / pelvis zone have firmness and / or height adjustable, while the other zones are provided with a firmness / fixed height. The thigh / knee, calf / lower leg and foot / ankle zones can in this case be provided as three zones, as two separate zones or as a single zone.
    [0035] However, the zone configurations discussed above are provided only as examples and other zone configurations involving more or less zones are also viable.
    [0036] Preferably, the zones that have firmness and / or independently adjustable height extend over essentially the entire width of the mattress and are separated in a longitudinal direction of the mattress. Such modalities are illustrated in Figures 2a, 2b and 2c. However, in case the bedding has to be used by more than one person at the same time, or if there is a need to distinguish between different lateral positions for other reasons, areas that have variable firmness / height and which are also separated in the wide direction. An example of such a zone configuration is illustrated in Figure 2d. In this case, seven zones in the longitudinal direction are provided, as in Figure 2b, however, in addition, each longitudinal zone is also separated into three zones in the wide direction. Thus, in total this modality comprises 21 zones that have independently controllable firmness and / or height. Again, the zone configuration discussed above is provided as an example only, and separation into two zones in the width direction is equally feasible, as well as more than three, such as four, five or even more zones.
    [0037] The sensors are preferably arranged on top of the mattress. Various configuration arrangements are feasible, depending on what type of sensor is used, and how fine resolution is required. In Figures 3a to 3c, some alternative configurations are illustrated schematically.
    [0038] In Figure 3a, the sensor arrangement providing a sensor area 31 in each zone is illustrated. As a result, the pressure that is applied on each zone is determined. In Figure 3b, the sensor arrangement provides three sensor areas 31 'in each zone is illustrated, the sensor areas being separated in the width direction of the mattress. Therefore, the pressure that is applied on each zone is determinable, but in addition, it is possible to determine how the pressure in each zone is distributed between the center and the sides. In Figure 3c, the sensor arrangement comprises a set of 31 "sensor areas within each zone, the sensors within each zone being separated in both the length and width directions of the mattress. In the exemplary embodiment of Figure 3c, 5 the sensor areas are provided in the long direction, and three sensor areas in the wide direction in each zone, providing a total of 15 sensor areas within each zone, however more or less sensor areas can be used , and the sensor areas can also be arranged in different patterns. The number of sensor areas need not be the same in all different zones either.
    [0039] The sensors are adapted to measure a physical parameter related to the lying position that is used by the user, such as a physical parameter that is proportional to the weight exercised by the user on the mattress, or that is related to the relative humidity, temperature or similar. The measured information regarding the physical parameter is transferred to the control unit. The physical parameter can be, for example, pressure, weight, deformation, temperature, air humidity, etc. In this way, by means of the sensor, the weight submitted to the bed arrangement can be measured, or other variations that occur due to a change in the lying position. The measured information is used as a basis for adjusting the firmness and / or height of the zones, as will be discussed in more detail below.
    [0040] Several different scales can be used to create the sensors. For example, one or more of pressure gauges, piezoelectric extensometers, capitive meters, magnetic meters, piezoelectric meters, optical meters, potentiometric and resonant meters, thermocouple meters and thermistor meters can be used. The sensors can be placed inside the mattress, below the mattress or on top of the mattress.
    [0041] In an exemplary modality, the sensors are created as a set of sensors that is arranged on the mattress surface. For example, the sensors can preferably be arranged in a flat and flexible sensor wrap can be arranged on top of the mattress. The sensor envelope may have an electrical impedance characteristic that varies according to a normal force exerted on it. Such a sensor arrangement is shown schematically in Figure 4. In this case, the sensor envelope includes an electrically conductive upper and flexible plate 61 comprising one or more electrically conductive sensors 62, an electrically conductive flexible lower plate 63 comprising one or more more conductive sensors 64, and a flexible intermediate layer 65, such as a piezoresistive layer, which has a region with active sensor that has an electrical impedance characteristic that varies according to a normal force exerted on it. The intermediate layer 65 is located between the upper conductive plate 61 and the lower conductive plate 63. The upper and lower plates 61, 63 are here coupled in a conductive manner to the intermediate layer. The sensors may preferably have non-bilateral current versus impedance characteristics. voltage. The piezoresistive layer can be created, for example, as electrically conductive particles suspended in a polymer matrix. The electrically conductive particles can be supplied, for example, with a coating that includes at least one metal oxide, metal oxide, such as copper oxide, to thereby form with said layer a PN semiconductor junction. The wrap is preferably made, at least partially, of an elasticly stretchable material, and preferably, of a stretchable fabric. Examples of such sensor wraps that can be used in the bedding discussed above are those described in U.S. 8,161,826 and WO 2009/120270, both said documents being incorporated herein by reference.
    [0042] Based on the information received from the sensors, the control unit 5 is arranged to determine in which position, among a series of predetermined lying positions, the user is at the moment. The series of predefined lying positions preferably comprises at least two, and preferably three lying positions which correspond to the user who lies on his back (supine position), with his belly turned upwards (leaning position) and on his side. However, more than three lying positions can also be defined. For example, different lateral lying positions (for example, the reclined lateral position) can be defined, such as lying with the body straight or bent / bent forward or backward. It may also be possible and necessary to distinguish between a left lateral position (such as the left lateral reclined position) and a right lateral position (for example, right lateral reclined position). In addition, it is possible to distinguish between different arm positions in the leaning and supine side positions. For example, it can be distinguished if the arms are arranged along the body, out of the body, on top of the body and / or if they are arranged under the head.
    [0043] Some studies indicate that the lying positions most commonly used for sleeping are: • Fetal position, that is, a pronouncedly folded / curved lateral position (41%); • Position of the "trunk", that is, a straight lateral position with the arms along the body (15%); • "nostalgic" or "homesick" position, that is, a slightly bent / curved lateral position, with the arms directed laterally in the same direction, and away from the body (13%); • "Soldier" position, that is, the supine position, with the arms along the body (8%); • "Free fall" position, that is, the leaning position, with the arms directed upwards along the sides of the head (7%); and • "Starfish" position, that is, the supine position with the arms directed upwards, along the sides of the head (5%).
    [0044] These and possibly other lying positions can preferably be identified by the control unit.
    [0045] The different lying positions and / or the different firmness / height of the variable zones can be predefined, or they can be defined and configured once and for all during manufacture, or during an initialization carried out, for example, by the seller. However, preferably at least a series of lying positions and the parameters of firmness / height can be defined by the user, and it is also possible that they will be reset and restarted over time.
    [0046] For this purpose, the control unit is preferably operable in a parameter setting mode, in which the predefined firmness / height values for the different zones in the different lying positions can be defined and / or adjustable. It is also preferable that, in parameter setting mode, the series of predefined lying positions can be defined and / or redefined.
    [0047] Through this, the user can register the parameter definition mode whenever he wants and in the parameter definition mode and he can adjust the firmness / height values for different zones and different lying positions, he can define new ones lying positions, or cancel previously defined lying positions. This can be done, for example, by the user who lies in bed and who assumes any lying position. The user can then adjust the firmness / height manually in the different zones until a comfortable definition has been obtained. The lying position and the firmness / height values for the different zones can then be stored. This can be repeated for the other lying positions. Alternatively or additionally, a previously stored lying position can be retrieved, and the firmness / height of the different zones can be adjusted and then stored.
    [0048] For communication with the control unit, a remote control 7 can be used, which is adapted to communicate with the control unit, for example, via a wireless interface.
    [0049] The control unit can also be arranged to store, when the series of lying positions is defined or reset, the sensor data from the sensors that correspond to the predefined lying positions, and to use the stored data to distinguish between positions predefined lying when in an operating mode. This can be used to predefine how different lying positions should be identified in general, regardless of the specific user. However, since the user with considerably different weight, height and body shape can use the bedding, it is preferable to define these values and / or relation (s) individually for each user.
    [0050] Allowing the user to define by himself the various lying positions that must be recognized by the control unit and to define the desired firmness / height of the zones for each of the said lying positions is a relatively simple and straightforward way of configuring the control unit operation. Typically, the user will be fully aware of which lying positions he uses most often. Thus, the user will, as an example, consider, in principle, a first position among these lying positions, and will define the desired levels of firmness / height for each zone through, for example, a remote control. When the user is happy with the result, he will store the configuration by activating an appropriate control on the remote control. As a result, the control unit will store this as a first lying position, along with the firmness / height levels of each of the zones for said lying position, and together with the sensor data obtained when the user was assuming this lying position. This is then repeated for one or more lying positions. When the desired number of lying positions has been stored, the user exits the parameter setting mode, and enters an operating mode. In this case, the control unit monitors the registration of the sensors, and determines, based on the stored data related to the stored lying positions, the lying position that most resembles that currently assumed, and controls the firmness and / or height of the zones with the levels of firmness / height stored for said lying position.
    [0051] The sensor data for a lying position can vary slightly when obtained when the mattress firmness / height levels have been adjusted to match this lying position, and when the firmness / height levels are still adjusted for another previously assumed lying position. However, in any case the control unit will normally be able to distinguish between these lying positions. However, in the case where a large number of lying positions have been stored, and / or if several relatively similar lying positions have been stored, the control unit can still store the sensor data to a lying position both when the mattress is defined in this lying position, as well as when it is defined in other lying positions. For example, it is possible to store the sensor data for each predefined lying position and for each setting of the firmness / height value that corresponds to those predefined lying positions. In this way, if the three lying positions a, b and c have been defined, and they correspond to the firmness / height definitions A, B and C, respectively, the sensor data to distinguish between different lying positions can be stored for lying positions a, b and c using the definition of firmness / height A; for a, b and c using the firmness / height definition B; and for a, b and c using the definition of firmness / height C. As a result, the distinction between the different lying positions becomes more precise. In an additional or alternative way, sensors smaller in number and sensitivity can be used.
    [0052] The control unit can be arranged to determine, based on the registration of said sensors, the current lying position of a user in a continuous or regular manner. For example, the control unit can continuously monitor the sensor data, and assess whether a change of lying position has occurred, or it can make such an assessment on a regular basis, such as every 15 or 30 seconds, every minute, or similar. However, in an alternative or additional way, the control unit can be adapted to determine, based on the registration of said sensors, the current lying position of a user when it is determined that a sensor registration of any of the sensors is changed in comparison to a last value stored in the sensor from said sensor by a magnitude that exceeds a predefined limit value.
    [0053] The control unit can also be arranged to record and store sensor data. As a result, the raw data from the sensors can be stored, and / or the aggregated data provided by the controller based on this sensor data can be recorded. For example, any given change in lying position can be recorded. The stored data can then be used to assess a user's sleep, for example, with a doctor, a sleep consultant, or the like. From the analysis of such data on sleep, it is possible to determine various sleeping problems and it is possible to provide solutions that can improve both the quantity and quality of sleep.
    [0054] When the control unit has determined that a new lying position has been assumed by the user, it can preferably be programmed to wait for a specified time, such as a few seconds, before adapting the firmness / height to the new lying position. For example, the control unit may use a waiting time in the range of 1 to 60 seconds, and preferably 5 to 30 seconds, and more preferably 10 to 20 seconds before responding. As a result, unnecessary variations in firmness / height are avoided, for example, when a user assumes a new lying position for a short period of time and then immediately returns to the previous lying position, when a user assumes an intermediate lying position by a short period of time before assuming a desired new, similar lying position. In this way, a change very often in firmness / height is avoided, so that the transitions become more subtle and less noticeable.
    [0055] With reference to Figures 5a-c, a mattress with seven zones is shown when used in the lateral position, in the prone position and in the supine position, respectively. In the following, reference is made only to firmness. However, it should be understood by the reader versed in the technique that corresponding effects can be obtained through variations in height, as will be discussed in more detail below. In this way, the increase in firmness corresponds to the increase in height, and vice versa. In the lateral position, as shown in Figure 5a, the shoulders exert the greatest pressure on the mattress, and a relatively high pressure is also exerted by the pelvis. A commonly preferred definition of firmness for the areas is one with a relatively firm area for the head / neck, a relatively soft area for the upper shoulder / back, a relatively soft area for the lower back, a relatively soft area for the buttocks / pelvis, a relatively firm area for the thigh / knee , a relatively firm area for the calf / lower leg and a relatively soft area for the foot / ankle. In the bent position, as shown in Figure 5b, the head exerts the most intense pressure on the mattress, however, in general a relatively regular pressure distribution is provided. A commonly preferred definition of firmness for the zones is one with a relatively soft area for the head / neck, a relatively firm area for the upper shoulder / back, a relatively firm area for the lower back, a relatively firm area for the buttocks / pelvis , a relatively firm area for the thigh / knee, a relatively soft area for the calf / lower leg area and a relatively soft area for the foot / ankle area. In the supine position, as shown in Figure 5c, the head and buttocks provide the most pressure on the mattress, however, a lot of pressure is also exerted by the shoulders. A commonly preferred definition of firmness for the zones is one with a relatively soft area for the head / neck, a relatively soft area for the upper shoulder / back, a relatively firm area for the lower back, a relatively soft area for the buttocks / pelvis, a relatively firm area for the the thigh / knee, a relatively soft area for the calf / lower leg and a relatively soft area for the foot / ankle.
    [0056] In Figures 5a-c, the seven zones are called AG, starting with zone A of the head / neck. On a mattress that has 10 different levels of firmness for each zone, where 1 is the softest level and 10 is the firmest level, the following firmness values can be used as an example for the lateral position (Figure 5a), the leaning position (Figure 5b) and the supine position (Figure 5c), respectively.

    [0057] However, as discussed above, preferred definitions vary from person to person and the definitions of firmness discussed above are provided as an example only.
    [0058] The mattress can be of various types, such as one that comprises inflatable elements, elements with resilient foam, resilient rubber, elements filled with water, and the like. However, preferably the mattress comprises a plurality of spiral springs, and preferably spiral springs arranged in separate pockets of a cover material to define a spring mattress in pockets.
    [0059] In a mattress formation with pockets of the present mattress, each zone is preferably arranged as a mattress with separate pockets, assembled together. However, a mattress with continuous pockets extending over several or all zones is also viable. Each mattress with pockets preferably comprises a plurality of strings interconnected side by side by means of a surface fixation, such as adhesive, solder, velcro or the like. Each rope comprises a plurality of continuous casings / pockets, formed by a continuous material and separated from each other by means of transverse seams, such as welded seams. Each wrapper / pocket contains at least one, and preferably only one helical spiral spring. The springs can have a spiral turn with a diameter of approximately 2 to 10 cm, and preferably 6 cm.
    [0060] However, as discussed above, it is also possible to use other types of mattresses in the bedding discussed above.
    [0061] The variation in firmness and / or height in such mattresses can be obtained in several ways, as previously known. Some examples of such provisions will be discussed shortly below.
    [0062] With reference to Figure 6a, the zones that have variable firmness can be created by arranging the spiral springs 161, for example, in pockets, on support plates 162 that have variable height. The height of the support plates can be controlled by rotating elements 163 disposed under the support plates, and which have a decentralized axis of rotation. As a result, by rotating the rotating elements, the plates assume various height positions. The top surface of the mattress can be attached to the base 164 of the bedding, so that the height difference of the support plates provides various levels of pre-tensioning the mattress elements. Such means of adjusting firmness are discussed, for example, in U.S. 3,340,548 and U.S. 2011/0258772, both documents being incorporated herein by reference.
    [0063] As shown in Figure 6b, a similar arrangement can be used for varying the height of the zones. In this modality, there is no fixation between the base 164 and the upper surface of the mattress. In this way, the difference in height of the support plates provides corresponding differences in height on the mattress surface. Variation in firmness is often preferred, since because of this, the mattress surface will maintain a smooth and flat upper surface, which in most cases is considered more pleasant. However, the support effect in relation to the user is more or less the same, regardless of the firmness or height of the zone (s) being varied. In addition, variations in height are often easier and less costly to implement.
    [0064] In addition, it is also possible to vary both firmness and height at the same time, for example, partially restoring the displacement of the top surface of the mattress.
    [0065] With reference to Figure 7a, the zones that have variable firmness can again be created through the arrangement of spiral springs 171, for example, in pockets, on support plates 172 that have variable height. The height of the support plates can be controlled by displacement members in the form of linear motors, winches, and other types of suspension mechanisms. Again, the top surface of the mattress can be attached to the base 174 of the bedding, so that the height difference of the support plates provides various levels of pre-tensioning of the mattress elements. Such means of adjusting firmness are discussed, for example, in the A.U. 55 13 00, U.S. 4,222,137, U.S. 2006/0253994, WO 99/65366 and EP 2,245,967, all documents being incorporated herein by reference. Similar to the above discussion in relation to Figures 6a and 6b, the arrangement in Figure 7a can also be used without fixing to the base, to provide a variation in height instead of a variation in firmness.
    [0066] With reference to Figure 8, the zones that have variable firmness / height can be created by means of inflatable elements 181, in which the pressure varies independently by means of pressurizing means 182. Such means of firmness adjustment are discussed, for example, in WO 2009/120270, said document being incorporated herein by reference.
    [0067] With reference to Figure 7b, the zones that have variable firmness / height can be created through a combination of inflatable elements 192 and other resilient elements, such as spiral springs, for example, arranged in pockets. The pressure in the inflatable elements varies independently by means of pressurizing means 193. Such means of adjusting firmness are discussed, for example, in U.S. 5,133,539, said document being incorporated herein by reference.
    [0068] Other means of adjusting firmness and / or height are also feasible, such as by placing threads or tapes along the mattress, so that the position and / or height tension is variable, as discussed, for example, in US 4 667 357, said document being incorporated herein by reference.
    [0069] The firmness / height adjustment means are operable, preferably, by a drive unit, such as a drive motor that electrically and / or pneumatically controls the firmness / height of the various areas of the mattress.
    [0070] To automatically change the firmness / height of one or more zones, the control unit can vary the firmness / height until a predetermined sensor value is obtained, which corresponds to the desired firmness. Preferably, however, firmness is controlled by choosing the position that was stored during configuration or in parameter setting mode. In this way, a moving part can be moved until a desired position or height has been assumed, or similar. Alternatively, a drive unit can be controlled to provide a number of revolutions or rotations, or the like. It is also possible to use pulse meters or similar.
    [0071] A person skilled in the art will understand that the present invention is in no way limited to the preferred embodiments described above. On the contrary, various modifications and variations are possible within the scope of the appended claims. For example, it is possible to use alternative mattress elements in the zones, such as resilient elements made of foam, rubber, spiral springs, spiral springs with pockets, inflatable elements, and the like. In addition, sensors can be created in several different ways, and the control unit can be configured in several ways.
