## Customer Reviews

### ⭐⭐⭐⭐⭐ Well worth it
*by K***Y on January 14, 2026*

Very comfortable and eases lower back pain

### ⭐⭐⭐⭐⭐ Cushion
*by L***Y on January 16, 2026*

Excellent, perfect, very comfortable

### ⭐⭐⭐⭐ Inconsistent Product.
*by C***A on August 15, 2022*

Im giving this product 4 stars instead of 5 because the quality is inconsistent. I’ve ordered 2 so far: The first one I ordered is perfect. Im sitting on it right now and it delivers everything it promises. I have hypermobility (my doctor thinks I have EDS) and have struggled with piriformis syndrome which causes a lot of sciatic pain whenever I sit. I sat on a cushion from a brand that rhymes with “blurple” and it was AMAZING, except for the expensive price tag. I scoured amazon for the closest affordable dupe and chose this one. The cushion is thick, comfortable, and cradles my butt bones and evens out the pressure of my rear end when I sit. I’ve taken it on airplanes, in the car, and when I’m sitting at work. It makes sitting bearable for me, so I can’t recommend it enough. Around 2 months later I ordered another one for my mom, but when it came it was much stiffer and not as comfortable. They might’ve changed the material that the insert is made of, but it’s nowhere as squishy as the first one I bought. So, if the odds are right and you receive a cushion like the one I got the first time, you’re in for a treat. If you receive a cushion like the second one I bought it’s not as good.
