After just a few days this flattened completely. :-/

Within 10 seconds, I started to feel fasciculations in my calf, knee, and thigh. This product may be for some people, but it is not for everyone

This foam seat did not alleviate pain or numbness. It felt for a short time after sitting on it, but then I began feeling the pain that I do sitting in my desk chair alone. This product did not work for me.

Hard as a brick. Not a bit comfortable. Returned it.

I find no comfort with this. Considered sending it back right away but I just hadn't got around to it.

Too hard foam. Not happy with this product. Spoke to sales representative and said it would soften up but never did. Sorry I kept this should of return it.

Seat is too thick and too short between back and where it hits me on the legs (and I’m a short person). Absolutely no use. Because of above I cannot use for sciatica pain. Just a waste of money. Would send it back but don’t know if I can.

The front of the cushion cut into the back of my thighs causing cramps I my legs. Very uncomfortable and unreturnable.

Not helpful with pain relief. Cushion flattens almost instantly. Waste of money.

I purchased this as my doctor recommended that I get one to help with the coccyx issue i recently started having. I tried this on my wooden chairs or regular sofa and it just does not work. I have not had any relief from this. I will be putting this back to resell and try something else.
