Review on 🪑 Ziraki Coccyx Seat Cushion Orthopedic: Ultimate Comfort for Back Pain Relief, Sciatica, and Tailbone Support - 100% Memory Foam Luxury Chair Pillow. Perfect Gift for Home, Office, and Car Drivers. by Mary Alvarado

I was looking for something for my office chair and found it looks good and the price is not bad. Boy was I wrong! This thing was rock hard and not an inch soft. I sat on it for a few hours thinking I needed to break it in and broke my ass instead. You can bang it on the table and hear a loud/hard bang. It's like someone soaked it in water and put it in a freezer to freeze it. Who thought it was "memory foam" meant to be slapped with a seat cushion? Revain would like the items they sell and/or ship to be screened prior to sale as this is common. This should not be marketed as "memory foam", but as a doorstop or self-defense tool. Hope that helps.
