A piece of furniture includes a rectangular frame for supporting a plurality of sinuous springs. A plurality of clip assemblies are secured to opposed side walls of frame. Each clip assembly comprises at least two metal fasteners, each having a generally planar head and a shank for insertion into the frame. The generally planar head of each metal fastener is encased by plastic of a non-metallic piece. The non-metallic piece has a hook to secure one end of a sinuous wire. Connectors may be formed with the plastic or non-metallic pieces to join multiple clip assemblies.

A combined sofa in a steel structure includes a sofa base, a backrest connected with the sofa base and a sofa armrest arranged on at least one end of the sofa base, wherein, the sofa base comprises a seat base frame, on which spring assembly is laid. The backrest is detachably connected to the rear side of the sofa base. With this design, during transportation, the backrest and armrest of the sofa can be disassembled, and the sofa base can be disassembled into one or a plurality of independent seat base frames, which is very convenient for transportation. The seat base frame(s) can be combined again as required for use to realize variable structures.

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.
