ABSTRACT:
A pressure reduction mattress intended to prevent and/or treat pressure sores includes within a cover a middle layer made of a densified polyester fiber, a top layer disposed on the middle layer and having a foot support section and an upper body support section, and a bottom layer disposed beneath and adhesively bonded to the middle layer and made of high density closed cell vinyl nitrile foam, the bottom layer extending fully beneath the upper body support section of the top layer but not beneath the foot support section. The foot support section and upper body support section are each made from respective upper and lower sheets of high density open cell foam, the upper sheet of each support section being softer than the lower sheet thereof. The foot support section has a convoluted upper surface, and the upper body support section may optionally have a convoluted upper surface. The middle layer is free of connection to the top layer.
