The FoamAD anti-decubitus mattress reduces the counteracting force of the body and is suitable for use in hospitals and nursing homes. The profiled upper and lower mattress surface is suited to flexible bed slats. The reinforced longitudinal mattress edges make moving the patient more easily and offer a better seating support on the edge of the bed. 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. Owing to its design, the mattress can be turned in all directions.
