Fits in my chair perfectly
I was super surprised by how much this cushion fit both my chair and my medical needs so perfectly. After recovering from sciatica I needed something to make sure I sit correctly and not stress my tailbone and this cushion has been wonderful for relieving the pain I was getting from just sitting on a regular throw pillow. Go figure! I love the material too. Haven’t had to wash it yet.

Great product
My tailbone hurt very badly so I ordered this pad to sit on and it is a wonderful comfortable pad. And I love the handle that I can hook onto my walker using the hooks I bought from Amazon when I go out so I don’t have to carry it with me. I am temporarily needing to ride the little riding cart in the stores and this pad works great since so many of them are bumpy. Very sturdy foam. Highly recommend!

I like the cushion softness
Works for me although I had to buy two to get enough padding. I appreciate the softness. Another Coccyx cushion I bought was way too firm.

Much harder than I expected
I bought this seat cushion for my senior citizen mom, as her wheelchair was not comfortable to her very thin behind. I hoped this cushion would be a soft, comfy padding for her to sit upon, but it is too firm. In fact, it is more firm than the seat of the wheelchair we were trying to cushion and pad. The foam is hard and rigid. Mom has no extra fat, and her bony behind needs softness and cushioning. Not the fault of the product. If you desire a firm cushion, this pillow will be exactly what you want. But if you’re looking for softness or squishy comfort, this isn’t that pillow. I gave the pillow to a friend who lives it, because she wanted a firm seat cushion. I will say the material Is good quality and the manufacturing looked like quality sewing g and construction. It just didn’t suit my mom’s desired level of softness and squishiness.

You want to make yourself comfortable try this!
I primarily bought this little seat to use on airplanes. I cannot travel first class. It seems as so, in the rest of the seats. I don’t know if it’s my imagination, but I think that took some stuffing out of the seats. The seats are hard and when you’re traveling, this little pillow is magic !

Terrible product. Does not stay in place.
First off, you CAN'T return this thru Amazon. Second, the seller DOES NOT answer any request for a return label or ANYTHING ELSE. I have messaged them several times in the past few days asking for a return. NO RESPONSE. DO NOT BUIY THIS PRODUCT. There is no non-friction material to keep this cushion in place on a seat. I sat on it for 10 minutes and slid all over the chair every time I moved. I tried it for another few minutes in my car and I could have been killed as it did not stay in place and I nearly fell off the seat forward as I came to a stop. TERRIBLE PRODUCT !!!!!!!!!!!!!!!

Good cushion!
Over the last 15 years. I bought a couple of these. They’ve lasted a long time and have been great. This new one however, is better than all of the previous ones because it’s so sturdy and supportive. It’s great for every chair, including the car. I was so happy to discover this on Amazon because I thought they weren’t making them anymore. They are real back savers.

Absolutely fantastic!!
These cushions are wonderful! My mother ordered her first one about three months ago: she has an L1 lumbar fracture and diabetic nerve pain, so her tailbone gives her a lot of grief. Before this pillow, she tried a number of different things (air & foam cushions, donuts, towel nests, etc), but was pretty much in agony unless she was standing up. But this cushion works like magic at giving her some relief. We just bought a second one about a week ago so she could leave one in the car instead of carting it around with her everywhere. It gives her the support she needs without putting pressure on her tailbone, and encourage her to sit up in a more ergonomically correct position which helps keep her from aggravating her spine. She uses it pretty much 14-18 hours a day, and the first one still hasn't gotten flat -- still going strong.
