These things go under sofa cushions to provide a firmer and more supportive feel, OR deal with a sofa whose springing has started to soften over the years. It consists of 15 boards (90mm x 470mm) which concertina out within a vinyl cover. When folded out fully, it is 1.5M wide. This one came from a smoke/pet free home and was previously used on a three seat sofa. It could be cut down to fit something narrower.
