Abstract
Welding is carried out by applying two electrodes having two flexible foam plates of different thicknesses placed on either side of a rigid frame, to the plastic envelope of the cushion under vacuum. The electrodes delimit the internal volume and the external form of the cushion by the contour of the frame. Two foam plates surround the frame and two sheets of plastic surround the whole to be welded at the edges. The envelope may be decorative and transparent. The process gives cushions of improved wear resistance and protects the corners against heat.
