Belmint Coccyx Seat Cushion

This is an excellent seat cushion. I weigh 210 lbs. I use it for extra support in an office chair. It is firm enough not to compress too much but still very comfortable and the gel keeps it cool. Excellent value for the price. I also like that it is big enough to cover most of the seat. One thing about it is common to all memory foam seat cushions, that it lasts for about a day. So you need to have another cushion to swap out and let it sit to regain its firmness (just like running sneakers). If I alternate cushions every other day or two it works perfectly.
