Not as firm as needed.
Bought this when I injured my tailbone. I don't see how this could work for anyone over 100 lbs, as it doesn't support weight over that. It is not firm at all. I use it now in my car to give me a little extra support, and it seems to help somewhat in that regard, but was completely useless at my desk at work- which is what I purchased it for. For the price, I don't feel I got what I was expecting. I would gladly pay double the amount I paid for this to have something that actually helps.
