A Quality "cush" for one's "tush"

I keep this Foam Coccyx Pad on the seat of the recliner chair which I often use and find that it provides significant relief for my lower back. i bought it some months ago and still feels and looks like a new pad. I also use it sometimes as a booster pad on the seat of my dining chair.

I like it so far...

So far it works. It is firm and about 2½" thick, but somehow it works. Not as much lower back and hip pain as I usually have whenever I have to stand. If anything changes I'll report back. Have a lovely day.

Works great!

I was very skeptical that this cushion would help my tailbone pain. However it is a god send! I have been in pain for weeks now and since I got my cushion it is gone! This product is a miracle!!
