Mesh Highback Support Cushion Breatha

As it is not stable on its own, you should also put a seat cushion on it so that your bottom doesn't slip.

I bought this for my husband, who says his posture gets bad when he sits on a chair. He was pleased with the cushion, so I've also put one on the zaisu-zushi (Japanese-style floor cushion).

I had a bad back and it was really helpful, but it's only black, so it doesn't match my chair, and I thought it would be nice if there was at least an off-white one to brighten up the room. It's quite good, with no slack.

I gave it to my boss, who has a bad back, and he said it was great.

It's thick and you can fix it in place with the belt, so it's convenient.
