good support for sciatica
I have sciatica and need a new chair for my office.  Have been able to put that off because I now have this cushion.  Also, I usually have to recover for a day after a 5 hr drive to  visit relatives, but last time I drove even farther and did fine because of this cushion.  Love it.  And it always pops back, no squishing noticed, and I'm no skinny minnie.
