A cushioned load bearing seating surface includes a suspension layer, a membrane and a load distribution layer. The membrane is positioned between the suspension layer and the load distribution layer. The membrane includes a base and a plurality of molded, oriented, piston-like projections extending from the base. The membrane defines intermediate portions between each projection and the base that extend in a direction opposite the projections. The projections are compressible from a first state to a compressed state under load and return to the first state upon removing the load. The intermediate portions flex to accommodate at least a portion of the projections as the projections are compressed. A molded, piston pixelated membrane and a method for making the membrane are disclosed.

A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.

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 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.

An office, work and leisure chair and retrofit kit for subliminal motions of the seated person. The chair has a cruciform base (1) with rollers (4), a pneumatic spring-action post (2) with an interface plate (5) for a seat panel (21) and seat pad (19), and a backrest (22). The seat panel is mounted with wobble capability on a pneumatic cushion, which has deformable air chambers (18, 35) connected by connecting hoses (27) and lies on an elastically deformable hollow body (14). The hollow body pumps the air chambers when a person sits down and stands up. A pump hose (12) with a one-way valve leads from the hollow body to compensate for leakage losses. Connecting hoses between the air chambers have valves (31; 75; 89) such that the wobbling distance of the seat panel and the damping of the wobbling motion is variable.

Office, work and leisure chair and retrofit kit for causing subliminal movements of the person sitting thereon. The chair has a cruciform base (1), freely articulated rollers (4), a gas-spring support (2) and an interface panel (5) resting thereon as a support panel. Mounted on the support panel is a base panel (28) bearing a seat cover (19) with a seat surface and back rest (22). The seat cover is provided and allowed to wobble, resting via a cover panel (27) on a plurality of spring elements (7), which are displaceable radially, or obliquely in relation to the radial direction, or helically from the center of the base panel to the periphery of the base panel. The spring elements are mechanically, hydraulically, pneumatically or electrically displaceable, so that the wobble distance of the seat cover and the attenuation of the wobble movement are variable.

The present application provides a cushion having a core layer and a quilt support/comfort layer. The core layer may comprise innersprings, foams, air cells, or combinations thereof. The support/comfort layer comprises a sleep layer that simulates a conventional quilted fabric layer. The sleep layer includes a thick, comfort fabric and a backing fabric, which backing fabric may be the same as the thick, comfort fabric. The sleep layer is formed by coupling the thick, comfort fabric to the backing fabric to form a plurality of individual pockets in which micro spring coils are placed. The micro spring coils have less uncompressed height than conventional innerspring coils. The sleep layer coupling is formed by spot coupling without using a metal needle to stitch the layers together. In other words, the spot coupling may comprise an adhesive or weld.
