Not bad but far from perfect
I like the cushion. I can sit on furniture that for years previously I could not because of the lack of support that would result in lower back pain. Now with the purple i can sit there pain free.. My only complaint is in a gaming style computer chair with racer style seating that curves up around the hips, this cushion doesn't work as well. It ends up creating more tension on the hips which can become painful. On flat surfaces though its amazing. Considering the back pillow next!
