Various systems and methods for adjusting the firmness of a spring mattress are described herein. Inflation elements having fingers may be coupled with a spring layer of a mattress to provide for inflating or deflating the fingers in the interstitial spaces defined by a group of springs of the mattress. Increasing the fluid pressure inside the fingers increases the lateral pressure on the springs. The increase in lateral pressure in turn increases the force required to compress the springs, ultimately resulting in increasing the firmness of the mattress. Conversely, decreasing the fluid pressure inside the fingers decreases the lateral pressure on the springs, which decreases the firmness of the mattress.

A mattress with adjustable hardness comprises at least one resilience supplying module, at least one air bag module and a lining provided for the resilience supplying module and the air bag module to be placed therein. The lining is provided with a plurality of lattice-like units, each lattice-like unit defining a mounting space therein. The resilience supplying module is provided with a plurality of elastic bodies respectively provided in one of the mounting spaces. The air bag module is provided with a plurality of air bag units respectively provided in one of the mounting spaces. In this case, the air bag units may be inflated consistently, and the expanded volume of each of the air bag units after inflation may be limited to be uniform by the corresponding lattice-like unit. Thus, the problem of incapability of being kept evenness after inflation in the conventional practice is solved.

An elastic pad for furniture can be customized and assembled by a user. The elastic pad includes an outer cover, an elastic module layer and at least one elastic pad layer. A side enclosure of the outer cover is detachably connected with a top cover body, and the side enclosure is detachably connected with the bottom cover body. The elastic pad is configured to allow a user to select a desired type and/or a desired number of elastic module layers and elastic pad layers, and to further select the side enclosure based on a thickness of the elastic module layer and elastic pad layer, and assemble the top cover body, the bottom cover body, the selected side enclosure, and the selected elastic module layers and elastic pad layers together to obtain the elastic pad.

The disclosure relates to a bunk, in particular for a vehicle cabin. The bunk comprises a base plate, an upper layer, a plurality of supporting members vertically compressible and spaced apart from one another substantially over the whole surface of the bunk, a plurality of pressure sensors which are part of the upper layer and in an adaptable area comprising at least one area of the bunk, a moving mechanism configured to move at least some of the supporting members in the adaptable area parallel to the base plate, and a control unit connected to the pressure sensors and the moving mechanism. The control unit is configured to cause the moving mechanism to move the supporting members in the adaptable area as a function of the current pressure data provided by the pressure sensors, to locally change the density of the supporting members to provide a locally variable bunk firmness.

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).

An adjustable mattress structure comprises a mattress body in which there are a plurality of hollow bases, a plurality of elastic support units, a plurality of adjustable positioning boards and a plurality of spring positioning bodies. Each of the elastic support units consists of a first encapsulated elastomer and a second encapsulated elastomer. The first encapsulated elastomer depends on spring positioning bodies to be fixed on one of the hollow bases so that the second encapsulated elastomer extends inside the hollow base. Each of the adjustable positioning boards is fixed inside a hollow base and used to receive a second encapsulated elastomer; the adjustable positioning boards in the hollow bases are situated at distinct positions by which the adjustable positioning boards make the elastic support units generate distinct resilient bearing capacities for adjustable mattress firmness supporting a body curve.

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.

A mattress includes a spring extending between first and second points to provide a first spring rate in a first direction. A polymer fiber structure is provided between the first and second points and adjoins the spring. The polymer fiber structure includes fibers interlinked with one another to provide the second spring rate in the first direction. An example method of manufacturing a mattress is provided that includes arranging springs to provide a mattress innerspring. A polymer fiber structure is introduced in a first state to the innerspring to provide an assembly. The assembly is further processed and the polymer fiber structure is simultaneously altered from the first state to a second state.

An elastic pad for furniture can be customized and assembled by a user. The elastic pad includes an outer cover, an elastic module layer and at least one elastic pad layer. A side enclosure of the outer cover is detachably connected with a top cover body, and the side enclosure is detachably connected with the bottom cover body. The elastic pad is configured to allow a user to select a desired type and/or a desired number of elastic module layers and elastic pad layers, and to further select the side enclosure based on a thickness of the elastic module layer and elastic pad layer, and assemble the top cover body, the bottom cover body, the selected side enclosure, and the selected elastic module layers and elastic pad layers together to obtain the elastic pad.
