Awesome it is just what I needed. It is comfortable and fits perfectly.

Absolutely love this Seat/Back Cushion w/Elastic Strap. I am using it as a Seat Cushion (replacing a portable cushion) & it is wonderful that it has a strap to secure it in place on my office chair. No more sliding around ! It is very comfortable for sitting long hours in front of my PC - reduces fatigue & back pain. The fabric covering is not slippery like my portable cushion was (it's going into my car). The cover is removable & hand washable. This is a wonderful ergonomic office chair seating system!

Works but a little tricky to keep on my chair.

cushion has layers of foam which can be removed to fit the amount of support needed. Pros: good color, adjusts to chair

Daughter loves it. She uses it in her car so she can reach the peddles
