A mattress 10 that provides an edge support feature that remains firmly supportive throughout bending of the mattress on an adjustable foundation, while also providing a flat, tailored finish for the side of the mattress. The mattress has a base, an upper surface, and two side walls extending between two end walls such that the base, upper surface, side walls, and end walls define a cavity comprising a mattress support, such as a spring unit, that supports the upper surface above the base. The side walls and/or end walls comprise an edge support system having a plurality of overlapping edge segments.

The present invention 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 conical 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 invention further relates to a spring cushion having the spring module.

A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have pockets of different sizes before springs are inserted therein to accommodate for the fabric stretching due to some of the springs exerting greater force on the fabric than other springs. The ability to create pockets of different sizes enables springs of different strengths to be inserted into the pockets along a string, the string having a generally uniform height after assembly.

Present embodiments provide various open coil spring assemblies which perform like an encased spring assembly. The embodiments have elastic lacings or connections which connect springs to springs or springs to lacings. Various spring embodiments are provided as well as various arrangements for the elastic lacings. All of these features improve compliance and stability while reducing motion transfer.

A pocketed spring assembly comprises a plurality of parallel strings of springs held together with tabs. Longitudinal seams joining overlapping tabs extend generally the same direction as the strings of springs. Pockets are formed along a string of springs by aligned separating seams. At least one spring is positioned in each pocket. Each separating seam joins opposed plies of the string and keeps the spring in its pocket. Ends of aligned separating seams are spaced from each other, thereby improving airflow between pockets.

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 bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The strings of springs may extend from head-to-foot or side-to-side of the product. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a branched end portion.

An internal spring system resiliently supports a mattress in an item of furniture. The spring system includes a system of sinuous springs arranged between upper and lower wire grids. A movable extender assembly is mounted on the grids to accommodate a longitudinal shift between the upper and lower grids during folding of the spring system between open and closed positions.
