Great! I was a little concerned when it came so tightly shrink wrapped, but a day or two later and it’s in great shape. It’s actually pretty comfortable, good angle. It’s a good width and pretty long to accommodate all body types. I like it can be two heights. My adult kids said it felt like memory foam. I can add my own pillow too to further adjust to my liking. I occasionally get bad heartburn or sick where I need to sleep sitting up. This helps me do that in bed. I tried using it every night at first because I usually sleep with two large stacked pillows, but I’m a side sleeper and it eventually hurt my neck. So, not great if you sleep on your side. I also just lay a pillow case across it to keep clean. You can unzip and take off the cover for cleaning, but I almost never get stuff like that back on right. I got the dark gray cover and I like the soft feel. I’m glad I got it.

Lifesaver while recovering from rotator cuff surgery

This pillow was a lifesaver, it’s sturdy yet comfortable and can be used many different ways! Great price and size too! I like that when I opened it, there was no smell! If you’re looking for a wedge pillow, this one will do the job!!

It is a great wedge pillow, but takes time to get used to sleeping on your back

Color: Dark Grey & White, Size: Adjustable 9&12 Inch + 1 Head Pillow

I bought this for post-surgery, I had to sleep on my back. Nearly impossible as a lifelong side sleeper. It is memory foam, and it does seem to run hot. But after a couple of weeks, I'm adjusting to it. Back sleeping is best for saving your face from AM wrinkles and mascara smears all over pillows. (Yes I know, I should take off mascara before bed, but....). Now that I've adjusted to sleeping with it, it stays on my bed and I wake up without the creases on my face and neck! So if you are buying pre-surgery, buy in advance to adjust to a new style of sleeping! I'm keeping it!

Its worth the purchase!

Color: Black, Size: Adjustable 9&12 Inch + 1 Head Pillow

Bought this pillow because Im dealing with both GERD and neck pain so I decided to order this and hope for the best thats being said Im so glad I did because its helped me a lot with both issues. Some extra comments: Its a little firm but not in a bad way and the head rest is comfy but I do wish I could bring it down lower.
