Abstract: An article of seating furniture (1) is constructed as a free oscillator having side members (6) with substantially Z-shaped resilient supporting sections (7), the supporting sections having a top end portion (9), a bottom end portion (8), and an intermediate portion (10) between them. The end portions (8), (9) of the supporting sections (7) are interconnected via a rod-shaped resiliently deformable reinforcing member (12) inclined oppositely to the intermediate portion (10) of the supporting sections. This construction prevents the chair from oscillating or seesawing excessively.

Abstract: A composite bar section for furniture and interior fittings is formed by two or more section bars and connecting elements, the connecting elements being inserted between two adjacent section bars, shaped and so undetachably interconnected, that on two opposite sides of the composite bar longitudinal slots are formed for housing randomly positionable connecting members of further components. As a function of the requirements, while using the same section bars, varyingly wide connecting elements can be used and consequently the cross-sectional shape of the sections can be varied.
