Butt Helper
I purchased 2. One for the seat at the computer desk and my SUV. I dont have back problems but I do find ways to drive my SUV more places than is actually necessary.  Lol. It cushions your butt, it feels like sitting on pockets of air which adjust to your butt. I took it to sit on the bench at a softball park and later at a playground and I could have sat there for another hour without needing to get up and move around. You wont regret the purchase.
