  • Patent number: 9055817
    Abstract: An article of furniture, such as a chair, including a free-swinging seat and a free-swinging backrest. The chair includes a seat and backrest coupled to a chair frame, where the chair frame includes first and second laterally spaced apart components. The first and second components each have a floor strut and a pair of legs that may be arranged in a substantially triangular configuration for supporting the seat. The chair also includes a coupling device, which may include a spring element, coupled to the legs and configured to allow forward movement of the seat and backward movement of the backrest, where movement of the seat and backrest may occur independently of one another. In some embodiments, the maximum movement of the seat and backrest may be limited by restricting movement of the coupling device.

  • Patent number: 8764116
    Abstract: An item of seating furniture contains a seat providing a seat surface, a generally circular foot panel positioning the item of seating furniture on a floor, and a central part, which connects the seat to the foot panel and of which a vertical center axis runs centrally through the foot panel. The foot panel is of at least partially convex configuration and that side of the foot panel which is directed toward the floor is configured, at least in part, as a non-slip surface. This creates an ergonomic item of seating furniture which stands in a stable state.
