AinivMemory Foam Car Seat Cushion for Driving - Coccyx Orthopedic, Breathable Booster for Long Trips - Black

This is a top quality car seat cushion, it came compressed in an air tight bag but overnight its taken its shape and the memory foam is amazing as it helps immensely with driving with a back pain especially on longer routes. I am extremely happy that i have found my solution after keeping several cushions for support which would end up flattening after a couple if uses. This looks good it has two elastic loops as seen in the picture that you can insert to the back of the seat to stop it from moving. Has added a little height to my driving and I can’t complain about it. Infact a few extra cms have improved my far vision while driving. Ticks all the boxes - value for money, back ache relief and smart product. Would recommend.

This cushion has a soft cover with a non slip underneath so it stays put on hard surfaces. On domestic chairs, it's not deep enough so only supports the top of your thighs. It works better as a lumbar support and it fits better in a car seat.The cushion needed to be left for 24 hours to gain its maximum depth. I measured this as 2 inches not 3 as stated on the web page. It has straps at the back which can be used to secure it to the back of a chair, but exactly how you do this is a mystery. Make up your own method.To be more effective, this cushion needs to be deeper so that it covers the whole seat that it's resting on.I hope you found this review useful.If you have a question, I always try to respond when Amazon forwards them to me.

not worth buying, uncomfortable

I have to spend up to three hours in a car regularly for work and in that time, a regular car seat can get a bit uncomfortable, This just adds some cushioning at the back of the seat.It does feel a bit strange to begin with, but you get used to it reasonably quickly. Sitting on it, does raise you up a little, maybe a couple of centimetres.It is held in place by a couple of plastic discs which go through the gap between the seat and the back.Overall, it does work quite well.

After a few days using it, it does the work very well. Not lift too high to reach the top of my car, could also stand it up to the back and to support your back. Very useful and functional. I like it very much

The Ainiv Car Seat Cushion has transformed my driving experience. The memory foam provides amazing support, and the coccyx orthopedic design has eased my back and tailbone discomfort. It’s breathable, stays cool, and gives a subtle lift for better posture and visibility. A must-have for long trips or daily drives! Highly recommended!
