The FoamAlthea anti-decubitus mattress is suitable for use in hospitals and nursing homes. It has been particularly designed for movable hospital beds. A three-dimensional-shaped foam core offers excellent pressure relief on critical body parts. The mattress cover is made of washable elastic material, which is breathable and permeable to moisture but prevents fluid penetration. The cover thus protects the core and also functions as an incontinence-proof cover that feels pleasant to the touch.
