Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core.

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 bedding device including: at least one adjusting unit able to adjust a height of the device; at least one human measurement module able to measure a three-dimensional surface morphology of a human and/or a quilt covering the human, obtain a three-dimensional point cloud of the human and/or a point cloud of the quilt, establish a three-dimensional model of the human and/or a three-dimensional model of the quilt, recognize each part of the human from the three-dimensional point cloud and/or the three-dimensional model; at least one sleep position determining module able to determine a sleep position of the human based on the spatial position and/or posture of each part of the human; and at least one form adjustment module able to control the at least one adjusting unit to adjust a surface form of the bedding device.

The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

In one embodiment, the digital bed system is comprised of an array of support cells. Each support cell is capable of communicating with a controller and increasing and decreasing in firmness in response to commands issued by a controller. The support cells are operatively connected to a communication channel that is also connected to a controller. The controller is capable of receiving data from the support cells and is also capable of issuing commands to each of the support cells. The controller is programmed issue commands to increase or decrease the firmness of individual support cells within the support cells.

Provided is an air-cushion block structure, and a mattress including the air-cushion block structure installed therein. The mattress of the present invention is provided with an air-cushion block structure which includes: an upper cushion having a first core hole vertically formed therein; and a lower cushion which has a second core hole vertically formed therein, and is disposed at a lower portion of the upper cushion. Accordingly, it is possible to stably transfer a weight of a user applied from an upper portion of the air-cushion block structure to a lower portion thereof, as well as, achieve a structure that stably supports the weight of the user by minimizing an occurrence of torsional deflection caused by the weight.

A piezoelectric adaptive mesh includes multiple piezoelectric fibers that include piezoelectric structures that can act as sensor and/or actuators to enhance a person's comfort. The piezoelectric structures communicate with a controller and/or a software processing system and may identify the position of a user and make adjustments through the actuators to increase user comfort by providing support, assistance, treatment, and/or temperature adjustment.

The invention relates to the field of beds or seats. In particular, the invention relates to a flexible element (10) stiffness that is adjustable stiffness along a compression axis (Z), the element including a compression spring (50). In order to enable the stiffness of the stiffness element (10) to be adjusted, it further comprises both a mechanism (150) coupled to the compression spring (50) so as to be actuated by compression of the compression spring (50) along the compression axis (Z) to move in a direction other than the direction of the compression axis (Z), and also an adjustment device for selectively restricting or releasing the movement of the mechanism (150). The invention also provides a unit (200) comprising a plurality of such flexible elements (10), and a method of adjusting the stiffness of the flexible element (10).

A support structure and vertical isolation structure may include a plurality of spring coils and a mesh network. Each spring coil of the plurality of spring coils includes a spring, a cap, and a floating connector. The cap is configured to engage the spring. The floating connector is disposed in a middle of the spring. The mesh network secures a first spring coil of the plurality of spring coils to a second spring coil of the plurality of spring coils by passing through the floating connector of each of the first spring coil and the second spring coil.

Variable stiffness apparatuses using an interconnected dual layer fluid-filled cell array. One example of the present apparatuses comprises: a substrate having a first side and a second side; and a plurality of structures coupled to the substrate, where each structure comprises: a flexible first portion having a first end, a second end, and a sidewall extending between the first end and the second end, the first portion defining a first chamber; and a second portion having a first end, a second end, and a sidewall extending between the first end and the second end, the second portion defining a second chamber in fluid communication with the first chamber; where each of the plurality of structures is coupled to the substrate such that the first portion is disposed on the first side of the substrate, and the second chamber is disposed on the first side or the second side of the substrate.
