Great for you bottom.
This cushion is great. It also works as a booster. I use it in my car and it cushions my bottom bones and helps me sit up higher so I can see better. I can't ride without it. I also like how it is shaped to me body.

Seat cushion for ischial bursitis
Boy, when I took this product out of the box it was hard as a rock. And it took a few minutes to remove the shrink wrap and other wrapping materials. But the more I removed, and the more the cushion expanded the softer it became. I hope it works

Decent cushion for sitting pain
I found this cushion to be mostly helpful. It causes you to sit higher in a vehicle, and as such it can be a bit difficult to adjust yourself as needed if you're driving. I think the effectiveness of the cushion depends largely on one's anatomy, but it does provide relief overall.

Great cushion to buy and use.
My husband has tried several cushions for his tailbone pain without success. This pillow works. Definitely has help with the pain.

Useless waste of money
Waste of money and useless unless you're an elephant. The sit bones are 4" to 6" As per pics open and adjusted closer it does not good and smooshes into a flat pancake. It going back.

Excellent product. I'm a happy lady.
Just delivered this afternoon. Ready to use this early evening. Immediate relief !!! Very comfortable finally. I've been using pillows and make-shift cushions, but nothing worked. I have a lot of paperwork to do this weekend. Perfect timing. Highly recommend this cushion for crafters as well. I'll be comfortable doing that too.

Bit to firm for me
I felt this cushion was supportive but to firm for my personal taste. It was as described and built sturdy and held up to my weight which is over 250lbs but it still did not provide any relief i gave the cushion to someone else whom liked it and it worked well for them so it was not an error with the product just preference. I prefer a softer and more plush surface especially for the pain i was feeling in my periformis muscle and this did not help my sciatica either. It actually caused pain in my legs for some reason which i think had to do with the shape. The person i gave it to was larger than me but weighed about the same and felt the cushion was just fine they use it for comfort in hard wooden seats.

A bit of relief for long sitting.
Too many car miles, sore "sit bone" not the hip or sciatic nerve, totally different. A bit of relief as holes do not compress the "sit bone". Had to have my PT instructor enlighten me.

Sit bone cushion
Nice and soft and comfortable to sit on. Not sitting on the bones anymore. Leaving it on the car seat over night in the winter freezees it and becomes rock hard. But within minutes thaws with the body heat and interior heating in the car and provides cooling effect on the butt.

O produto não eliminou nem diminuiu as dores
O produrto não eliminou nem atenuou as dores na posterior de coxa, joelho e panturrilha direitos cusadas pelo tendao isquiotibial. As dores ocorrem ao ficar sentado em casa e tambem com piora significativa dirigindo
