Beds may include environmental control components, which may be temperature control components and pressure adjustment components in some embodiments. The environmental control components may be configured, for example by a controller, to provide different sleep environments based on identity of sleepers using or expected to use the bed. The controller may receive information as to how to configure the components based on one or more sleep profiles for sleepers expected to use the bed. The sleep profiles may be received from a server, or received from a smartphone of a sleeper. The sleep profiles may be deleted from the bed after use.

The core elements (6), which are adjustable in respect of the hardness thereof, have an upper support part (7) having an upper support surface (8), a lower support part (9) having a lower support surface (10) and at least one pretensioned spring (23, 24), by the pretension force of which the upper and the lower support parts (7, 9) are held at a distance from one another. The pretension force of the springs (23, 24) is adjustable.

A pocket spring mattress arrangement, such as a bed arrangement, having adjustable firmness is disclosed. The mattress arrangement includes a pocket spring mattress having a plurality of pocketed units of coil springs individually arranged in pockets formed of a casing material. The mattress has at least two parts of which at least one is a compactable part. Further, at least one elongate actuation member extends perpendicular to a compacting direction for the compactable part(s), corresponding to a width or length direction of the mattress, and is embedded within the mattress between two of the parts. The actuation member is moveable in the compacting direction to expand or contract at least one of the one or more compactable part(s) of the mattress. Elastic elements may further be provided to contract one or more of the compactable parts.

The invention relates to the field of furnishing. In particular, the invention relates to a stiffness adjustment device movable between an interference position for imposing a restriction on the deformation of a seat, back or bedding spring, and a non-interference position for releasing the spring from the restriction. The stiffness adjustment device comprises a resilient element, e.g. such as a flexible blade and, as it moves between the interference and non-interference positions it passes through an intermediate position in which the resilient element is subjected to resilient bending that is greater than in the interference and non-interference positions.

A pocket spring mattress (1) comprising a plurality of double layer spring units (7) arranged in rows and columns to form a rectangular shaped mattress is provided. Each double layer spring unit (7) comprises a first pocket spring unit (2a) arranged axially onto a second pocket spring unit (2b), and each spring unit (2a, 2b) comprises a number of springs (3a-b, 4a-b) and a fabric pocket (6) enclosing the springs (3a-b, 4a-b). The springs (3a-b, 4a-b) comprises reference springs (3a-b) having a first spring constant and frame springs (4a-b) having a second spring constant being greater than the first spring constant, and frame springs (4a-b) are arranged in at least one of the first and second pocket spring units (2a, 2b) of at least one outermost row or column of the double layered spring units (7) in a configuration such that the edge of the mattress (1) is reinforced.

In systems and methods for adjusting the firmness of a mattress assembly and/or modulating the pressure in a mattress assembly, a mattress assembly includes: a two-dimensional array of bladders; at least one pump that is in fluid communication with the bladders to provide air and/or fluid to the bladders: multiple valves that are interposed between the pump and the bladders to control the flow of air and/or fluid to or from the bladders; a pressure sensor operably connected to one or more of the bladders; and a controller in communication with the pump, the valves, and the pressure sensors. The controller is configured to selectively actuate the pump and one or more of the valves, while receiving feedback from the pressure sensors, in order to adjust the firmness of the mattress assembly and/or modulate the pressure in the mattress assembly.

Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail via a load cell, a lead screw coupled to a rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. A tubular sock disposed over the main spring, and a compliant insert can be disposed between adjacent main springs to inhibit side loading and maintain the main spring in upright relation with the spring rail.

A multi-layer air mattress having an upper section with one or more layers of comfort material and a lower section having one or more layers of support material. A middle layer is arranged between the upper and lower sections and includes apertures for retaining air springs. The air spring has two cups that are sealed to a form plate to create a welded joint that encapsulates a sealed internal cavity. An invertible nipple is pressed into the internal cavity to reduce the cavity volume and self inflate the air spring.

A furniture device configured to receive the weight of a being, said furniture device comprising a holding arrangement (20, 120) and at least one section (30, 30,130) comprising a base (2, 102), a movable plate element (4, 104), a moving mechanism (6, 10) and at least one elastic device (12, 112). The plate element (4, 104) is configured to interact with the at least one elastic device and to be moved by the moving mechanism in respect to the base in order to adjust the firmness of the at least one elastic device. The elastic device comprises a pocket (14, 114) made of a flexible sheet material, and an elastic member (18, 118). The holding arrangement comprises a holding member (22, 122), which is fixed in relation to the base (2, 102) or the plate element (4, 104) and a connecting portion (24, 24,124) which is arranged at the elastic device (12, 112) and which connects the holding member to the elastic member. The elastic member (18, 118) exhibits a first portion (18a, 118a) arranged proximal to the free end of the elastic member, a second portion (18b, 118b) being arranged distal to the free end of the elastic member and an intermediate portion (18c, 118c) arranged between the first and second portions. The holding member (22, 122) is, via the connecting portion (24, 24,124), connected to the intermediate portion (18c, 118c) of the elastic member, such that, during movement of the plate element (4, 104) relative to the base (2, 102), the elastic member (18, 118) is compressed and relaxed only over the second portion (18b, 118b).

A mattress having variable height and hardness is disclosed. The mattress comprises a base layer held by a mattress cover using an extendable attachment system. The mattress further comprises one or more top layers made of resilient material which are stacked on top of the base layer. Only friction between the material of the top layers limit the lateral or longitudinal movements of a layer with regard to another layer.
