A seat assembly is provided having a seat bottom and a seat back mounted adjacent the seat bottom. A cushion is disposed on at least one of the seat bottom and seat back and defines a seating surface. The seating surface has a plurality of regions. A controller is in communication with the cushion and is programmed to independently vary a stiffness of each of the regions along the seating surface.

Method and apparatus for an improved sinuous spring for use on the seat box of a piece of furniture. The sinuous spring includes three pieces wherein a middle piece or section is placed in between a front and rear section. After the middle section is placed between the other two sections, the middle section would be folded so as to be disposed under one section and over the top of the other section and then clipped securely so that a single piece of spring having the correct length and tension is formed in the process.

Provided is a seat which offers increased ride comfort and less fatigue felt even on long-time sitting. The seat includes a cushion frame, a first support member supported by the cushion frame and configured to support a seated occupant, second support members disposed at left and right sides of the first support member and configured to be deformable, and a restraining portion by which each second support member is restrained in such a manner that its laterally outer side is less likely to sink down than its laterally center side. The seat is configured such that an upper-side support surface for supporting a seated occupant is so restrained by the restraining portion as to assume a first position when no occupant is seated, and to assume a second position when an occupant is seated, the support surface facing further inward in the second position than in the first position.

It is of interest to be able to adjust the upholstery firmness of furniture for sitting and lying on as individually as possible, in particular with a view to being able to use the furniture for a long time. In addition, there is a need for a design which allows firmness adjustment to be integrated and which can be realized as flexibly as possible for different furniture or seat variants. The invention provides an upholstered-furniture arrangement (100) which has a basic frame (7) and an upholstered cushion (6) on which someone can sit or lie, which is fixed to the basic frame at least in the edge region thereof and which has a panel (4) beneath it for upholstery-firmness adjustment, the panel being arranged in the basic frame (7) such that the height of the panel can be adjusted by pivoting the panel, wherein the end of the panel (4) located opposite a pivot shaft (14) is arranged freely in the basic frame (7), and a height-adjustment device acts on the panel (4) from beneath by applying an adjustable compressive/prestressing force (F), the height-adjustment device being supported in the downward direction by the basic frame, counter to the compressive/prestressing force. This arrangement has an attractive, direct technical effect and offers a good compromise between cost and benefit.

A self-adaption breathable cushion comprises a fixed base and a plurality of self-adaptive units integrated side by side and disposed on the fixed base; each of the adaptive units comprises a strap and an elastic member, the elastic member supports the strap to tension above the fixing base; when the strap is pressed and recessed, the elastic member deforms, so that the whole self-adaptive unit moves downwards; when the pressure is removed, the elastic member is reset, and the strap is also reset. The self-adaptive breathable cushion can be deformed self-adaptively according to the weight of a human body to be borne, so as to be attached to the human body, making the human body more comfortable.
