Abstract

The mattress is formed from rolled up sheets of plastics material (9) which contain several sealed gas filled cavities (2). The rolled up sheets are arranged in one plane and are secured to each other. The sheets may have a flat first side and may have projections on the other side which form the cavities. Preferably the projections face outwards when the sheets are rolled up. A sheet of elastomeric expanded material may be secured to the first side and a sealing coating may be applied to the other side. The rolled up sheets may be secured together by a cord (4), which passes around the circumference of the sheets and which may be knotted (5) between each sheet.
