Review: Works but your mattress will slide - I've used this for quite a while now and it helps with sleep apnea, but does not cause lower back pain like using a wedge pillow does. The stress on my lower back is mitigated by my thick memory foam mattress and topper. Unfortunately with a deep mattress this foam is exposed from your mattress cover and sheets. I didn't worry until my uncle died and I took on his cat who enjoys tearing it up. I recommend they sell a cover for the wedge so it isn't so much fun for cats to destroy with a non-slio top surface. My mattress slides about 5 inches away from the headboard pretty quickly on this thing. Moving it back in position is a lot of extra effort I won't be able to do in my golden years. Great price, wonderful product but needs a anti slip cover so the mattress doesn't slide and the cat doesn't just love scratching at the foam. It has retained it's shape over years but I am not particularly heavy.
Review: Full size mattress wedge. - Great product. Works perfectly!

## Questions & Answers

**Q: I am undecided between getting the 5" or the 7" wedge.  Has anyone tried the 7" and found it too high?**
A: I have the 7 inch.  I have only had it for a week, but I like it.  I cannot compare the 5 inch to it though  because this is my first wedge.  When I wake up during the night, I find that I have slid down some in my bed, but never to the uncomfortable stage.  I am sleeping  better though vs. no wedge at all.  I will probably never sleep flat again now that I have this one.  I have it on top of my mattress.  I may try it under my mattress someday to see which way I prefer to use it.  I hope this helps answer your question.

**Q: my dr wants me to use something that's 45 degrees - which would be more like 7" for reflux.  Does 5" work as well as 7"?**
A: So far my 5"  has been perfect.  I did have a wedge pillow that was 5 1/2" but since it was so short length wise I would slide down the pillow.  Since the mattress wedge covers the whole bed the slope is gentle and I stay at the top so the acid reflux has stayed down. So for me the 5" is perfect.

**Q: Can this work on top of the mattress?**
A: Yes, it works well. I have a queen size mattress and it works fine.  It does make a lot of difference when you have digestive problems.

**Q: Are the two halves for King size packaged separately?**
A: we ordered the queen size which were separated (rolled) in the same package

### ⭐⭐⭐⭐⭐ Full size mattress wedge.
*by A***R on January 13, 2026*

Great product. Works perfectly!

### ⭐⭐⭐⭐⭐ Well made, worth the money
*by C***N on July 1, 2025*

I’m so happy with this wedge. It was easy to put on, I decided to put it on top of the mattress but under the foam topper. It made the bed feel a little bit softer which is what was needed because I had been wishing for the best bed to be a bit softer. The mattress protector fit over everything, I don’t have a box spring just a 14” mattress. I laid on it and the angle was perfect, I worried that it would be difficult to get used to but it feels just right and should really help us with gerd which we both suffer from. It arrived very quickly and had no odor, I’m very happy that it is made in America, no toxic fumes. Don’t hesitate if you are on the fence Made in America
