Review: Saving my SI joint on the daily. - Saving my SI joint on the daily. I have used this particular cushion long enough to replace it twice and I love it still. The brand makes a seriously long lasting, comfortable, cushion that actually fits my butt. I have psoriatic arthritis and Ankylosing spondylitis, so a cushion with this sort of design has become necessary to my life. I'll buy again and again!
Review: Recommended - Good cushion for my office chair. Makes paying bills a little less pain in the butt.

## Features

- [Ergonomic Design] Perfect office chair cushion, 100% memory foam cushion helps relieve the pressure while driving or sitting for long periods. The ergonomically designed "u" shaped cutout keeps your coccyx suspended above hard seat surface, relieving pressure all along the back, tailbone and legs. It also helps promote healthy posture.
- [Premium Material] Different from other brands’ seat cushions that are too hard or lack of support, we put in more costs to increase the density of memory foam, which makes the cushion soft and supportive! When you sit on the cushion you would feel bouncy and comfortable just like sitting on a balloon.
- [Thoughtful Designs] Removable soft and skin-friendly cover, non-slip bottom, side handle (portable and convenient). The extended hidden zipper makes it easier to remove the cover, aesthetic and helps avoid your chair being scratched by the exposed zipper.
- [Wide Applications] Lightweight and durable car seat cushion, which is portable and applicable to various occasions, such as office chair, car seat, home chair, airplane seat, wheel chair and so on. It’s also a perfect gift for health!
- [Guaranteed Customer Service] We believe that you would like our seat cushion because it could bring you comfort and health. But if you meet any problem or feel unsatisfied while using it, please feel free to contact us and we would provide a 100% satisfactory solution for you in 24 hours.

Good cushion for my office chair. Makes paying bills a little less pain in the butt.

### ⭐⭐⭐⭐ Slides Around
*by J***. on August 7, 2026*

This works well for my car seat, comfortable yet firm and helps with my tailbone pain. I’m only giving 4 stars however as I wish it had a strap of some sort to keep it in place, as it slides around a lot.
