Alveo Semi Circular Half Moon Bolster Memory Foam Support Pillow for Head and Leg Support with Zip Cover, Sized 20 x 8 x 4.7 inches

I usually don't give bad reviews or am ever disappointed with items from Amazon, but I am sad to say that this pillow for $19 is not worth it. I have bad sciatica and find that sleeping with a good pillow under my knee helps me sleep better at night. I decided to look for a pillow specifically for this and went with this item. I was so excited for it that I even cut off the care instructions tag (and of course can't return it now).-It came in this little duffle like bag and the pillow was folded in half. This caused the form of the pillow to lose its shape.- if you're looking for something that can help elevate your knees/legs I suggest finding a more "fluff" and firm standard pillow. This half moon is no where near high enough to even fulfill my arch behind the knee. If I could compare what this feels like, I'd say fold a bath towel and put it under your knee.I have no idea what this pillow could even be useful for at this point. I'm hoping if it can't help me with my back, it'll be useful something else.

I was hoping this would have a little more height to it, as this doesn't really support my knees as well as I hoped it would. That said it is better than having a bulky regular-sized pillow under my legs. It's soft and comfortable, which is good - just not as much support for my knees as I needed.

The pillow is solid and works as expected. A little too hard for my tastes, and did not adhere well to my CPAP if I turned to my side. Flat on my back and positioned right, it did the job.

The media could not be loaded.  My first memory foam of any kind so figure start with something small so chose this half moon bolster like memory foam.When I took out of the package the pillow looked so small so I let it just expand to full regular size. Been using it as a pillow since I received it.It comes with a cover that zips open and close so you can wash just the cover and not worry about getting the actual foam dirty.

So far so good, great for back pain, knee, hip, ankle and joint pains. It has provided support for my knees and there's no long discomfort while I sleep and my knees don't seem to hurt as much during the day any more.This pillow is also an excellent neck pillow. It provides just the right firmness and support for the head and neck put it under the back of my legs and/or the small of my back fine it to be very supportive.

Takes a bit of getting used to and I actually prefer to sleep with one leg on the pillow and one leg off, to the side, but my sleep has definitely improved and I feel like my back is more aligned. This pillow was cheaper in price than another half-moon pillow on sale during Prime Day--I'm glad I went with this one. The washable cover is a huge plus, and it was ready to use right out of the vacuum-packed package.

Pillow worked great and the cover is attractive and easily washable. I can't comment on how it would work for other (more common) purposes, but it's very useful to give extra arm support for anyone spending time at a dialysis or infusion center. It could also act as a lumbar pillow to make long hours of sitting in a dialysis/infusion chair more comfortable. This could be a very thoughtful and useful gift for anyone in that situation.

Not the most comfortable pillow for me. This one is extremely rigid. I normally do like pillows on the firm side, but this is extra firm. Too uncomfortable for me but it may be great for someone else.
