Review on Samyoung Mesh Back Lumbar Support Cushion | Breathable Office Chair & Car Seat 12" X 16 by Jim Ledbetter

I have a rare disorder that causes severe joint damage and as a result, I have been a wheelchair user for many years. I recently switched chairs and I was using a memory foam back cushion. It was okay, but it held in heat. It is way to hot to have sweaty cushions. This is completely different. It has more structure than the smooshy foam and I like it a lot more than I expected. It keeps my spine straight instead of slouching over. The mesh helps to circulate air so I don't feel hot at all. I needed to shorten the back strap a bit, but I have a rather small wheelchair. I think it would work well for an office chair as well.
