A foam-cored cushion has a cover which regulates temperature, humidity and prevents the ingress of fluid. The lower part of the cover (1A) is fabricated of liquid-impermeable material which is waterproofed along all corners and edges, forming a trap for any fluids. The top and side covering panels are several millimetres thick and allow the passage of moisture and air. The foam rubber is a body shape-conformal substance. The foam is inserted or removed with the assistance of a sliding clasp fastener. |
