FOMI Extra Thick Firm Coccyx Orthopedic Memory Foam Seat Cushion | Black Large Cushion for Car or Truck Seat, Office Chair, Wheelchair | Back Pain Relief (Gray)

Great cushion for heavy person. It saves my butt from getting sore after sitting for awhile. Doesn't Slip and rebounds nicely once you get up. Appears to be well made. Good value.

This is an odd combination of it’s firm enough to be uncomfortable but soft enough it compresses almost flat after a short while. I’m back to searching.

Gives me enough height to see more clearly and drive more safely. Exactly what I was looking for!

I bought this because the ad said relieve hip pain. And, it does. Works great.

It is large and works initially however, after about 30 minutes it compacts down to be way to hard on your posterior. It might be because I'm too heavy for it at 250 pounds tho...

Taking the cushion out of the box, I could tell right away it wasn't going to work. Too soft. And sure enough, within a minute of sitting on it -- the cushion was completely flat and my tailbone was complaining. In fact, I couldn't even sit for the rest of the night.The cushion is thicker than others I've gotten, but thickness does no good if the cushion squashes flat upon sitting.I weight around 220, btw.Conclusion? Buy something else. This one is worthless.

Seems well built but under my 195 lbs it squishes down too much. Looking for a seat cushion that will hold its shape under my weight.

Do not expect it to be supportive - I bought it for a 120-lb. female.
