KOYOSO Car Seat Cushion, Car Seat Pad Memory Foam Mat for Auto Office Chair Back Sciatica Pain Relief - Black (1PC)

This is a good thickness, not excessive. This doesn't behave like any memory foam I've ever come across. I'd say it was regular foam but it works fine.As this is wider than your average car seat the thickness will push your thighs together and it's totally unbreathable so you're going to wind up with an extremely overheated crotch and posterior in no time at all.Good in principle. In practice I'd probably shop elsewhere.

good fit on my car seat but could do with a fastening system as it does move a little and needs adjusting every time I enter the car, does the job though, if a bit pricey!

This was a good, comfortable cushion, possibly could have done with being a little thicker. It did not have attachment straps, so it did move about a little, but it had a good grippy underside so it was not too bad in that respect.

This was bought for my father who has muscle wastage and sores on his bottom. Travelling in the car is much more pleasurable for him now - provides adequate padding, its well made and in my opinion well worth the money for comfort.

Loving this , I drive long distance in a hgv and this is well comfortable .

I suffer from bad sciatica and this cushion definitely makes a difference for the better.

Had a pain in my bottom and leg and bought this because we were driving to Italy . Well it was great and didn’t have any pain at all.Highly recommend this product.it just works!

I bet you would feel the different ride. Moves around on the seat but double sided sticky tape helps.
