Product Overview Overlays are an effective solution for a wide variety of conditions around client comfort, pressure care and sleep climate. Use as an underlay. This prevents bottom out and adds support. Use to make an existing mattress firmer. This can help with mobility and transfers. Use as a crash mat. Can be placed beside bed to reduce risk of injury. Alternating Air MattressesOverlays are frequently used with an alternating air mattress. When an air mattress is used on a profiling bed, the air pressure can change when the bed positions are adjusted. The XP Support Overlay is suitable to use under an alternating air mattress. When an air mattress loses pressure in profiled positions, patients are not left lying on the bars or mesh of beds. This can prevent pressure sores or injuries.
