Perfect Posture Pillows Best Memory Foam Coccyx Seat Cushion with Cooling Gel for Office Chairs, Car & Home - Orthopedic Seat Cushion Helps Relieve Tail Bone Pain, Sciatica, Back & Neck Pain Blue

Perfect fit in my car! I busted my tail pretty literally and I was worried about driving my manual car. SO happy I found a pillow I can sit on while driving!

if you sit on it for too long, you need to flip it to regain its shape again. needs to be more firmer.

Harder than expected. Works well, just wish it was "squishier".

really helps with my sitting for long periods of time

It certainly goes flat after sitting a while but seems to be doing the trick just fine.

A bit hard

Too hard!

I love this seat. I use it in my chair at work. I work in in a call center so I sit 7 hours per day. I have back problems and have broken my tailbone in the past. Since I started using using this seat, I do not have pain. I highly recommend it.
