Review on Ultimate Comfort And Support: Tsumbay Memory Foam Seat Cushion For Home, Office, And Car by Michael Floyd

Comfortable and prevents my butt from hurting even after many hours of sitting. I would have no complaints about it if the zipper on the covering would open up a few more inches. It would make a significant difference. As it is, you have to remove and insert the foam cushion with a decent bit of force since it's larger than the zipper opening.My advice is curl it into a bit of a U shape while you do so, and do so carefully. I could see it getting ripped if you pulled too hard although it seems fairly sturdy.Still a good product, but with minimal effort it could have easily been improved.
