My staples chair ($150 new, sale-priced at $79) is starting to flatten and the pan may be "sinking" a bit around the support.
A cushion may add some life, as it's functional enough otherwise.
I'm looking for
something like
this because after awhile, the edge of a chair starts to irritate the underside of my thighs and may contribute to cramps in my calves. This cushion looks large enough to stay put fairly well.
My next chair will have better seat padding (since I do not) and a slope at the front of the chair. My tailbone needs no particular consideration, though.
Most of the Amazon reviews of different products have the same complaints- no support or the cushion flattens out fairly quickly.
I also just ordered this
lumbar support but will place it vertically against the seat back.
I have an occasionally recurring back pain near/under my shoulder blade that is sore for three or four days. This makes sitting in a computer (office) chair very uncomfortable since they all tend to have a curved back that "cradles" my back. I've found that placing a cylindrical pillow down the back offers a lot of relief. But it doesn't stay in place very well, so this largish support (20" long) may fill the bill.
