A chair operable between an extended configuration and a collapsed configuration includes one or more legs, a handle and a locking mechanism. The one or more legs support a seat and the handle extends away from the seat opposite the one or more legs. The locking mechanism includes a lock plug disposed in an elongate trough. Movement of the handle between the extended and collapsed configurations involves depressing the lock plug and flipping the trough to an opposite side of the lock plug.

A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

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 body support structure includes a shell having a central region, an outer peripheral region spaced from the central region, and at least one array extending between the central region and the outer peripheral region. The at least one array includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The support members of the at least one array are progressively divided between the central portion and the outer peripheral edge.

A body support structure including a plurality of spaced apart support members defining a first surface and a plurality of spaced apart base portions defining a second surface. A plurality of connectors connects each base portion with the at least the two adjacent support members. In one embodiment, a body support structure includes a first plurality of spaced apart first support members and a second plurality of spaced apart second support members arranged in a checkboard pattern.

The present invention offers a type of chair cushion and its supporting structure, and belongs to the technical field of chair manufacture. It solves the problem of unreasonable design in prior art. The chair cushion and its supporting structure comprise a pair of side boards and a bottom board. The undersides of the pair of side boards are provided at both sides of the bottom board to form a mounting cavity in which are provided several elastic supporting components. Each elastic supporting component includes several vertical springs of identical size and shape and a first flexible cladding. All springs in each elastic supporting components are arranged in at least one row and cladded in the first flexible cladding. The advantages of the chair cushion and its supporting structure lie in that the elastic supporting components formed by the first flexible cladding that clads at least one row of springs promote the strength for supporting person's hip weight on the seat. Due to the promoted buffer capacity, the protection role is enhanced to the person sitting in the seat.

A chair operable between an extended configuration and a collapsed configuration includes one or more legs, a handle and a locking mechanism. The one or more legs support a seat and the handle extends away from the seat opposite the one or more legs. The locking mechanism includes a lock plug disposed in an elongate trough. Movement of the handle between the extended and collapsed configurations involves depressing the lock plug and flipping the trough to an opposite side of the lock plug.

A seating structure includes a shell having a central portion, opposite outer peripheral edges laterally spaced from opposite sides of the central portion, and at least one biasing array disposed between each of the opposite sides of the central portion and a respective outer peripheral edge. Each of the biasing arrays includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The biasing array may include a plurality of biasing arrays, with at least one connector connecting adjacent biasing arrays. A second shell may be connected to the outer peripheral edges of the first shell, with an open space defined there between. Each of the opposite outer peripheral edges is independently deflectable in response to a load being applied to the second shell.

Provided is a chair including a support member that is at least a seat body and a backrest to support an occupant. The support member includes a composite portion at least a part of an outer periphery of the support member. The composite portion includes a first outer periphery that is a part of the first member and a second outer periphery that is a part of the second member. The first outer periphery and the second outer periphery are arranged to overlap each other in a thickness direction of the support member. In the composite portion, at least a part of the first outer periphery is formed into a thin portion thinner in the thickness direction than a part located on an outside of at least the part of the first outer periphery in the first member.
