I love my Quickie 2. foam insert tires so i don't have to worry about inflation I use a Jay ez -- gel/foam cushion in it. I remember trying a heavy medium and light chairs and being told the differences when i was in the hospital…. the hospital chairs were just awful….. It was fitted for me --- important part of getting the right chair -- i remember all sorts of measurements and observations of how i sat etc.
Although my physiatrist says there are better options. I had shared the free online webinar on chairs -- it was very good. perhaps the transcript is available online if you google it.
