Welcome, and let me say, I hope you have better days ahead.

I would say the most important thing about wheelchair shopping is NOT to get the retail generic versions of chairs. Many here may not agree with me but I have experience in this. My first chair was an IC (Institutional chair) like you find at the airport or hospitals. They are unhealthy and can harm you more than help. They have virtually no cushion, they are heavy and have no lumbar support.

If you are so prone to pain, go to your primary doctor, or neuro, and ask them to get you a script for 1) a wheelchair and 2) a seating clinic evaluation. They will measure you in every direction and find the chair for you.

My first custom fitted chair I got on 9/11/01 Yep, that fateful day. It was an Invacare Pro-T which I still have in my garage. I went from that to a power chair (my arms got too weak to use manual) my first power chair (PC) was a Pride Flash, and my second chair was an Pride Quantum 6000. The Q-6000 is the BEST chair for PC's. I don't much care for the Pro-T (mostly because it is heavy and I don't like the aluminum tubing.

My next chair will be a TiLite ZRA. It is an all titanium rigid chair.

Since you need something that folds, there are MANY chairs out there, but the most important thing is that it be fitted to you.

I also endorse Jay cushions. I use both the Jay Basic and the Jay Gel. Both excellent support for long term use.

So, I hope that helps.
