This is horrible - ONLY fits on very large seat - NOT for a short person - VERY uncomfortable - don't waste your money on this one - also went flat within a week.

Got for mother and she said it was too hard. Sent back without any problems.

It didn't fixed my problem and felt uncomfortable within a week. I lost my original shipping bag so I didn't return. Wouldn't recommend to anyone, especially at $40 price point.

the cut out at the back is too large, and since the foam material is very soft, it does not support or hold its shape. Would not buy this one again.

Way too thick and wide for use in most seats or cars. Too thick in front it digs into your thighs and cuts off circulation to them.

This was too deep to alleviate my tailbone pain without causing my legs to ache. I am very sad and I wasted $40. My blow up donut is much better at helping with the pain but I was hoping this would work so I didn't have to embarrass myself by carrying around a blown up, red, donut all the time.

Too hard.

Did not help my wives back problem. She said it made her hurt worse.

Dislike this pillow. When you sit down, you slide right off.

Design is great, unfortunately, the foam is too hard! It should be much softer to be of any good use to those of us with back and pelvis issues. This feels almost like wood.
