"For those of you who have experienced skin/tissue breakdown from sitting while using wheelchairs, I highly recommend the cushions manufactured by EASE Seating Systems in Paradise, CA. Their cushions provide a unique, state of the art "active massage" by alternating pressure away from the critical areas while you sit. They not only prevent sores from occurring, but also provide a maximum healing process to wounds that already exists. If you have had a breakdown in this area, you know how difficult and frustrating it is to heal it. I have been using a wheelchair for over forty years as a result of a spinal cord injury from an automobile accident. I encountered my first pressure sore in this area about seven years ago. It took me weeks if not months to finally heal it but I am now experiencing frequent skin trauma in this area ever since. I heard from two friends with SCI about the wonderful results they were enjoying using the EASE cushion, so I purchased one. What a difference! Now I don't like being without one. This isn't a mass produced, or one size fits all cushion. The professionals at EASE customize the cushion to meet your individual body and sitting requirements to maximize effectiveness and promote ultimate healing. Call them and try the cushion for yourself - you will be glad you did."
