Review: Suprise!!! - So, I was a bit skeptical about buying a hunk of memory foam, for the price. But this cushion not only provides support, but it is also comfortable and really helps alleviate pain from an old injury. I play games online as well as banking and surfing. Surprise!!! My legs aren't hurting. Maybe I found something specific to aiding my injury...who knows. I'm satisfied. Couple of things I noticed...memory foam holds heat, so sometimes it's a bit warm and the size of the cushions doesn't fit my office chair very well. But still a great product.
Review: Easy to use, great support - I got these for my computer chair. Easy to use, soft, and retain their shape. I don't feel that it has a cooling effect, it's always warm in my opinion. Good quality memory foam, never flat, and is slip resistant. Easy to use, comfortable, and effective.

### ⭐⭐⭐⭐ Makes me feel like I have a UTI.
*by E***C on January 11, 2021*

I know that sounds really strange and is maybe really personal. But I have been using this butt cushion for about 5 months, and I know that it is the reason I feel this strange sensation. Firstly, I don't use the lumbar cushion because my chair is too small for it to strap on to. Secondly, I have good things to say about the butt cushion: 1. It really keeps its shape well. It is firm, and when left for multiple days (like a weekend or longer), you come back to a plump, firm, not-squished seat cushion. It is nice. 2. It feels comfortable, it really does. I actually really liked the hump that sits between my legs until I realized it was making my urethra uncomfortable. 3. The grips on the bottom!!!! They're awesome. It does not slide around. 4. The price is great. I bought this because my stool at work has a METAL BOTTOM, tiny surface area, and looks like it's from a torture chamber. I was very pleased with the quality for the price I paid. Until the discomfort began... So, somehow, the hump that exists in the middle that rests between the sitters legs pushes strangely on my nether regions and affects my urethra. I find myself feeling like I have to pee like all the time. Then, when I get up, it also still feels that way, and I experience a tad bit of discomfort even when urinating. The feeling lasts basically all day, even after I've left the seat cushion (on my drive home, for instance). It goes away in the evening and I never feel it on weekends. I tested out sitting in another chair at work all day and felt no discomfort. It's definitely this cushion. As soon as I sit down, now, I start to feel that strange sensation of needing to urinate, even if I just peed. I don't know if this matters, but I'm a plump, tall female. I have plenty of cushion on my legs and nethers already, so I can't imagine how a skinnier-than-I-am female could find this thing comfortable. I really want to like this thing because it does feel supportive and comfortable. But the uncomfortable feeling of needing to pee all day just isn't going to fly with me. I've ordered a new chair altogether.
