Just bought this for my chair a day ago and it's awesome. I love the thing. Got a $8 chair from goodwill, decent back support, but the seat and back cushions were flat as heel. I covered the back with a folded up blanket and sweater but the seat was always hard to find the perfect comfort level for. Got sick and tired of dealing with it so I shelled out $20 for this and it's been a hell of a purchase so far. It just brings comfyness to a whole new level on a work chair.
