Under Mattress Wedge for Acid Reflux, Queen Size Bed Wedge, Under Support & Mattress Riser, Memory Foam Top 7.5-Inch Head Riser Incline Topper, Non-Slip Bottom & Side Storage Pockets

I ended up putting the wedge UNDER the mattress, definitely more comfortable and I don't slide down the bed! Helping me to sleep better, less acid reflux!

Shipped quickly. Easy to place. Works as needed. Seems to be helping.

For me, it helps reduces snoring, backache and light headedness. I got both wide and narrow ones. The wide one works better under the mattress. I kept sliding down at night. Get the narrow one if you want to use on top of the mattress.

This was the nicest wedge I have purchased. The longer slope made using my own pillow possible while being elevated. The only problem I had was it shifted at night when my husband flipped and flopped about. Because I don’t have super-deep pocket sheets I couldn’t put the fitted sheet over the wedge to alleviate that issue. Otherwise it would have been perfect.

Updated initial review: Although this didn't work for me, their customer service is outstanding! 10/10 will recommend to other people.I bought this as someone who has has a very bad spinal condition and needed something to stay raised at night since converting from a recliner to a bed. I like how soft and how tall it is but the biggest problem is it's non-slip bottom, it is not non-slip. I constantly feel it moving around and sliding from side to side while trying to sleep which is frustrating. My sheets have the connector on the sides holding them in place and I still feel it sliding down nightly. Pretty disappointing.

Hard as a rock way past firm. No way to be comfortable to sleep on. So high can't use a pillow either. Not helpful for me. I recommend a softer foam.

Worked well just found out i need a lower incline.

Really good memory foam material. Fits my king bed perfectly. Just firm enough. Has not lost its girth. Perfect height and very comfortable. I don’t even need a pillow any longer.
