Lazyzizi Wedge Mattress Elevator 5-Inch Inclined Mattress Topper for Acid Reflux, GERD, Neck & Back Pain, Snoring, Under Bed Wedge Mattress with Washable Cover & Non-Slip Bottom for Bedroom, Twin

We bought this for our motorhome bed and it helps our gerds problem. It's comfortable and stays in place, comes with a nice cover that is not water proof so I put one on it. We have pets on our bed. It's worth the money!

works very well ,has trouble getting to 5 inch but 4 inches ok

LOVE IT's support and firmness - Must Add Velcro on the bottom so it stays in place.

I like this product-- it's a more dramatic incline than you'd think. I actually need a step stool to get into bed now (I'm 5'5"). I put the wedge under my mattress and it works well, but the issue I end up having with it is that it causes my mattress to shift around so I'm constantly having to shove the mattress back into place. As a result, the gap at the headboard is worse and I lose my pillows more often, so sometimes I end up with a sore neck because of lost pillows in the middle of the night. In terms of getting the incline though, it's very effective and I've had less problems with heartburn since sleeping with it. Imperfect, but definitely helps in the way I'd needed to. Better sleep quality, just a little frustrating to be having to adjust and fix the mattress-- might be better for someone who doesn't toss and turn like I do. Maybe a grippier cover on the wedge would help in future designs?

This item does what it’s supposed to do and definitely elevates the head of the bed. I wish I would’ve chosen the smaller elevation because I am a stomach sleeper and I think I would’ve been more comfortable. I know you can put this on top of the mattress, but I thought it might be, less likely to move if I wedged it between the mattress and the boxspring. I wish I didn’t have to use one, but this one was affordable and definitely did the trick.
