This cushion's design gives you a very solid seating posture and helps you sit straighter in your wheelchair. It is very comfortable because of the adjustable air pressure that you can control. This has been the best cushion that I have found in over 50 years of becoming a quadriplegic.
The only downside of this cushion is that it is pretty expensive. But like the old saying, 'you get what you pay for'. The only caveat especially for quadriplegics is if you struggle with your balance then this might be too much for you to handle the challenge of sitting this straight.
I'm a 6 ft 4in quadriplegic that needed better stability in my cushion. I was constantly wrestling to stay centered with my regular ROHO cushion,
