well, i thought i would write about my thoughts on the jay j2 wheel chair seat cushion, the one i have is a deep contour cushion, and has treated me very well! i have used one for all 10 years of being in a chair, and so far i will not try another one. why you ask? because i have NEVER, i repeat NEVER had a pressure sore! how awesome is that? well i never had one from a bad seat cushion, i got a small one when i rode atv for a week straight and it was really bumpy and the seat on it wasn’t the best! so thats why i got that one. but as for the wheelchair cushion, i recommend the jay j2 deep contour cushion for its maximum stability and awesome softness
