Abstract: The method of manufacturing an explainable element for use as a support body of a piece of furniture or a part thereof, a mattress, a cushion or the like. The element was a thin wall of a soft, flexible polymeric material, by blow moulding in an essentially closed form. During the blow-moulding process at least one portion of the wall of the element is pressed inwardly to a position where it is brought to permanently adhere to another portion of the wall of the element or another portion of the wall which is pressed inwardly.

Abstract: A container element for a furniture item, including at least one thin-walled closeable support element being fillable with air or the like from a collapsed condition to an expanded condition, the element forming support structure and/or a cushion for a piece of furniture as an arm-chair, a sofa, a bed or the like.

Abstract: In a furniture article consisting of a back rest, seat and foot rest the foot rest is pivotally moveable between a position in which the foot rest is held substantially horizontally outwardly from the seat, and a position in which the foot rest abuts against the seat. This is achieved by a frame work holding the seat support material, which frame work consists entirely of side edge rods having hinges between the seat and the foot rest portion of the side rods, the frame work having no transverse rods which could decrease the physiologically acceptable seat functions and comfort of the article in any of said foot rest positions. The back rest portions of the side rods are provided with hinges which permit the back rest to assume two positions, one with a high back rest and the other with a low back rest having a portion of the back rest abutting against the remaining back rest surface, without any comfort decreasing transverse rods existing in either of said back rest positions.
