## 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 7" 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 PBDEs, TDCPP or TCEP (“Tris”) 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 chlorofluorocarbons (CFCs) Performance-tested Durability-tested Emissions-tested Content-tested Analyzed by independent, accredited testing laboratories Meets CertiPUR-US standards for content, emissions and durability, and are analyzed by independent, accredited testing laboratories

Review: Great simple solution - A very simple, but a great effective solution. I have tried many different gadgets and products for people with GERD and this is the best. Highly recommended!
Review: Avana mattress elevator helps me sleep at night (GERD relief) - I'm dealing with GERD and need to sleep elevated at night. I tried a wedge pillow which was uncomfortable because I'm tall and it wasn't long enough for my torso. So I thought I'd give the Avana mattress elevator a try. At the lower-end price, I didn't care about having to return it if it didn't work out. Needless to say, that won't be an issue because this is just what I was looking for. It arrived yesterday and I slept on it last night. I'm 6'3" 200 lbs and didn't have any slippage during the night. However, that could be due to the Impressions memory foam mattress topper that sits on top. We bought the CGK Unlimited extra-deep CA King sheet set which covered the 24" head of the bed.

## Questions & Answers

**Q: does this have a longevity warranty? how long will it maintain its shape without being compressed?**
A: I have had my king size for a year. There is me my Great Dane and a Goldendoodle sleeping on it for a total of about 425 lbs a night. It doesn’t compress, slide, or move. The mattress doesn’t slide on it. It is the best solution I have ever had.

**Q: Maxium weight. My boyfriend is a big guy. Will it hold up under large/tall?**
A: Not sure there is a max weight for this item but I a m over 300lbs and it seems to be holding up fine. I've had mine for over a year at least.

**Q: Do you carry a California King size base?**
A: They now the California King sized. But good luck trying to find the matching covers. I bought the California King elevator but cannot find covers for them- not even from other brands

**Q: I do not have a box spring in my bed. My bed is made out of wood slats with the matress on top of the wood slats. Will the Avana matress still work?**
A: I use mine between wood slats and a sleep number mattress. It works great. It is firm enough that the mattress sensors work normally.

### ⭐⭐⭐⭐⭐ Avana mattress elevator helps me sleep at night (GERD relief)
*by A***N on 28 June 2026*

### ⭐⭐⭐⭐ Would prefer 5” instead of 7” Cal King
*by H***S on 3 February 2022*

I bought this for 3 reasons: - Help with partner’s acid reflux - create a downhill run for the urinal hose to drain into its jug - make it easier to take pills and swallow water while lying down. We have a motion base, but tilting that up at the head causes back pain and difficultly sleeping on my side. This keeps us sloped while essentially lying flat as far as spine curvature goes. The extra height is a bit of a problem, so I will have to remove one more section of the bases legs to bring the overall height back to around 20” in the center. The head will be around 24, and the foot closer to 17” Overall, it has accomplished what I wanted and we both are sleeping better and the urinal is draining perfectly now. I think a 5” height would have been just as good. Only the Chinese suppliers offered that, but only in standard eastern king, not Cal King, and I didn’t want to cut it
