Review: Super cushiony tush saver ! - Have you ever sat in a hard wood chair for long at an elementary school? I have and it's not fun! It saved my tush & back from aching. This was well worth it's price. Good quality, you sink down in it in comfort, the size is perfect an the front slants slightly to accommodate your legs. It's not heavy - I carried it to the gym in the school where I sat on the floor with the kids. It's a nice black and would be perfect in an office chair, car seat, or even on a bleacher seat at a game.
Review: Firm but cushy - I ordered the larger of the two sizes offered and it's the perfect size for my office chair. Lifted my butt 3 inches which caused my legs to rest at a much more comfortable angle. Wished I had bought one of these a long time ago. It's pretty stiff, but does have cushion to it. when I ordered it I was afraid it would be too mushy. But it's not.

### ⭐⭐⭐⭐ Comfortable!
*by S***I on January 12, 2026*

Love how comfortable the cushion is. It does not quite conform to my car seat as the back is square instead of curved. But still love it.
