A spring module for a furniture cushion includes a conical spring and a double-layer flexible sleeve. The double layer flexible sleeve has a frustoconical first outer layer having a first closed top end, a first open bottom end, and a first outwardly extending flange at the first open bottom end. A frustoconical second inner layer inside the frustoconical first outer layer has a second closed top end, an open second bottom end, and a second outwardly extending flange at the open second bottom end of the frustoconical second inner layer. The conical spring is between the first outer layer and the second inner layer. The spring module may be attached to a base having locking structures for locking adjacent spring modules together.

An upholstered article is described, especially construed as a mattress 1.1, with a lower layer 2.1 and an upper layer 3.1 and intermediate elements 4.1, 4.2 arranged between the lower layer 2.1 and the upper layer 3, 3.1, wherein the intermediate elements 4.1, 4.2 each comprise a profile axis 6 extending transversely to the longitudinal direction of the upholstered article, wherein, in a cross section 7.1 perpendicular to the profile axis 6, a first intermediate element 4.1, 4.2 provides a first outer contour 8.1 along its periphery, and a second intermediate element 4.2 comprises the same outer contour along its periphery as the first intermediate element 4.1 or a second outer contour 9.1, wherein the first outer contour 8.1 comprises a first contour portion 10.1 with a nonlinear course facing towards the upper layer 3.1 or towards the lower layer 2.1 and wherein, in the first outer contour 8.1 and/or the second outer contour 9.1, at least one counter-contour region 11.1 is present, of which the course is complementary at least in one part to that of the first contour portion 10.1.

A spring module for a spring cushion for furniture. includes a base (20), an end cap (30) and a spring (10) arranged between the base and the end cap. The end cap has a flexible connection portion (33) and is configured to be detachably fixed to the base (20). The flexible connection portion (33) is located radially inside the spring (10). The spring module provides improved stability. The spring cushion has a simple structure and is easy to assemble and disassemble. The disassembled spring modules can be compressed or stacked and nested to save storage and transportation space

An elastic pad for furniture includes a mounting layer, a plurality of elastic modules, an elastic balance net and a flexible cover. A plurality of raised blocks are arranged on a top surface of the mounting layer. Each elastic module is nested on one of the raised blocks, where an outer diameter of the raised block is greater than or equal to an inner diameter of the elastic module at a corresponding height. This allows the elastic modules to be mounted independently of one another. For example, if an elastic module is damaged, it can be removed for repair, without removing other elastic modules.

A spring module includes a spring and a spring bracket for accommodating the spring. The spring bracket may have a base, an end cover and a flexible connecting part connecting the base and the end cover. The spring may be fixed in the spring bracket with a predetermined initial pressure. The spring module may be used in a spring cushion for furniture.

The present disclosure provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present disclosure further relates to a spring cushion having the spring modules.

A customizable mattress includes a chassis defining a cavity. A spring pack is removably positioned within the cavity. A top pad removably covers at least a portion of the spring pack. In some embodiments, kits and methods of use are provided.

An elastic mattress for furniture includes one or more elastic modules and one or more bottom layers, the one or more elastic modules comprise a plurality of pre-compressed springs, middle parts of the plurality of pre-compressed springs are disposed with connecting members, adjacent pre-compressed springs of the plurality of pre-compressed springs are connected to each other by corresponding ones of the connecting members, connecting structures of side surfaces of a corresponding one of the connecting members of the plurality of pre-compressed springs comprise one or more first connecting structures and one or more second connecting structures, the one or more first connecting structures and the one or more second connecting structures are disposed on adjacent ones of the side surfaces of the corresponding one of the connecting members, and bottom surfaces of the plurality of pre-compressed springs are connected to the one or more bottom layers.

Described is an improved active suspension to give an additional spring to an overlying mattress, including an elastic element including a central body, a plurality of flexible arms extending in a cantilever fashion from the central body and a raised perimeter portion connected to the flexible arms and supported elastically by them, a member for supporting the elastic element, designed to be mounted on a slat.

The disclosed technology includes tiered void cells which provide protection, comfort, and stability during compression. The tiered void cells may be arranged in vertically stacked columns and include a stroke whereby tiers of a void cell can telescope into adjacent tiers of that void cell, as well as telescope into adjacent tiers of adjacent void cells in a column. Implementations described and claimed herein include a cushioning system comprising an array of tiered void cells, wherein each tiered void cell includes a base portion, a plunger portion, the plunger portion to collapse into the base portion under compression of the cushioning system, and a living hinge elastically connecting an inner perimeter of the base portion to an outer perimeter of the plunger portion.
