“I bought two of these for side sleeping support for my legs or arm. I'm glad I got a pair, because now the opposite reviews of them being overly soft and too firm make sense. One is quite soft. After about a month it became a little softer and saggier than I'd prefer between my knees, though it's not too bad and I use it sometimes. I've tried sleeping with the other, but it's quite hard. I tried to sleep with it, hoping it would break in, but it didn't with the few uses I forced myself to make. I use it to support another pillow if I prop myself in bed. It's pretty obvious that their quality control isn't what it needs to be. On the plus side, the covers look nice.”
“I tried the knee pillow first and that was an immediate reject. So I tried this. This one I can at least use under my knees when I'm laying on my back. But it's almost totally useless for side sleeping. Both their products simply jack up my knees too high, causing my hip to be out of alignment in the reverse. I'm keeping it for when I need the back support but it's a waste otherwise.”
“This is fine as an under knee support but is far too hard for side sleeping. It actually caused back pain. It seems most of these bolsters are made of the same rock-hard memory foam, unfortunately.”
