Why most cushions go flat
Cheap foam stops pressing back after a few weeks.
Then you are sitting on the chair again, with a thin pancake between you and it. This one is built around three things you can check with your hands.

Nothing presses on the bone you sit on.
The U-shaped gap at the back sits under your tailbone. Your weight lands on the thighs and hips instead.

Both hips at the same height.
Flat seats let one hip drop. The contoured sides hold both hips level, so your back is not twisting all day to fix it.
Press it. Let go. It comes back.
High-density memory foam. It molds to you while you sit and returns to full height when you stand. A cushion that stays dented is done.
Where it goes
It stays on the seat. You get up without stiffness.
Non-slip base on the bottom. No straps, no setup. Put it down and sit.
