I have air pockets where 3 of my spinal discs use to be, so comfort and support is critical to my functionality. I've had the Procar Lowback seats in my truck for somthing like 8-10 years now, and they still look and feel like new. Previously, I had very expensive Recaro seats. They lasted 3 years and broke down to the point I couldn't drive the truck. I have a 9 year old Honda CR-V and the original seat has worn to the point I can't drive that either. So I just ordered an adapter bracket and will be installing a Procar Lowback in that one as well (I have a spare since I've also made office furniture out of these).
If I found something better I'd probably buy it, but from my experience these seats are great, and very inexpensive compared to others on the market.
