Review on KENNISI Cooling Durable Cushion 1 Black PJ by Mark Sutovsky

Easy to fit, just hang over the seat and around the headrest. I wish there was a way to tie the seat together for more stability, but it has a pad that can be placed underneath to reduce shifting on the seat. Overall it's not great, I don't really think it's as effective as a back and problem area massage. I think the beads are too small. With this setup you don't feel much pressure on your back. I'm quite a tall guy, 6'0", 240. I think if you're a slim or bony person it "might" have a bigger impact.
