The reason why I designed this cushion, is because I didn’t like any of the cushions that were on the market these days. They gave me red skin easily. My body is almost completely paralyzed, so I don’t move, and I’m quite tall, thus my risk of getting pressure wounds is very high. For some 5 years I tried everything I could think of, you name it and I have considered it. The final design is quite simple to make, not easy but very doable. I have been sitting on it for about 15 years now, which makes me the living proof that it works!
