## Overview

The Avana Mattress Elevator is a 5-inch high-density polyurethane foam incline designed to fit king-sized mattresses. It provides a gentle, therapeutic elevation that naturally alleviates GERD and acid reflux symptoms without medication. Made in the USA with CertiPUR-US certified foam, it ensures safe, eco-conscious comfort. Easy to install as two foam slants, it supports restful, uninterrupted sleep while reducing your carbon footprint with minimal packaging.

## Description

A night of uninterrupted sleep does more than offer our bodies a chance to recuperate from a long day; our minds and spirits are also rejuvenated by those blissful hours of slumber. However, achieving such a peaceful night of rest can be difficult, particularly for those of us who suffer from GERD or Acid Reflux. The Avana Mattress Elevator may help through natural elevation. Your whole torso is gently lifted by our resilient under mattress supportive foam, providing an ideal inclined sleep surface. Our precise 5" inclined angle will send you down the path towards dreamland. Available in four sizes, the Avana Mattress Slant covers the entire length of a Twin, Full, Queen, or King Size mattress. Made from ultra-comfortable medium density polyurethane foam that gives you the perfect amount of support throughout the night. CertiPUR-US program assures that the foam is: Made without ozone depleters Made without flame retardants; Made without mercury, lead and heavy metals; Made without formaldehyde; Made without phthalates; regulated by the Consumer Product Safety Commission Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million) No CFCs; Meets CertiPUR-US standards for content, emissions and durability, and are analyzed by independent, accredited testing laboratories

Review: 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: This helped with my GERD and my husband hasn't snored since we've been sleeping on it. Liked it so much bought a second one for our bed at the lake. Didn't find it difficult to get used to sleeping on in the least. Also helped improve the bags under my eyes...bonus! Would recommend :)

## 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
