“We are care givers for my brain injured brother and he was starting to get pressure sores, he has become totally non ambulatory, at 41 years post injury so we purchased the Drive Medical Med-Aire Alternating Air Pressure Overlay System with Pump. It not only helped his existing sores heal but he has not had any new sores since using this mattress. We are leaving soon for our other home for 4-6 months and we will be ordering a second unit for that house.”
