Does what you expect it to do
I ordered this cushion after reading a couple articles ranking it high, especially on durability. My office chair has a weird bar right between my gluts and the backs of my thighs that causes pain and bruising. It definitely works well for this, and I no longer have tailbone pain. It also has helped my posture. However, after a week of daily use, it actually has flattened out a bit, even though it comes on the firmer end. I think for it being on the higher end of the price range other cushions are on Amazon, it could be a bit higher quality. I don't know if it'll last longer than those other cushions in its supportive aspect.
