Happy with my purchase!
I’m glad I bought this! No off-gassing for me and I have an annoyingly sensitive nose. Excellent quality, no sagging, no slipping as others have stated. I do have a bedskirt that is more like a legging, if that makes sense. It’s a knit fabric that goes around my box spring, like in a hotel. It’s big enough that it also covers this wedge. My only wish is that it was a little higher.

Do not buy this piece of junk... A total rip off... awful product
This is a piece of garbage. Bumps and low areas.

Cinvoice cured me of snoring!
I bought this for my Texas home. I have a Givanlee shorter mattress wedge in New Jersey. This full size mattress wedge has stopped my snoring problem. Prior to its use I snored 15 minutes a night and was diagnosed with sleep apnea. After I installed it in my bed, I had zero to one minute of snoring per night. I do not have to wear a mask for apnea now. I do not have to do anything else but use this wonderful wedge. The only minor problem is that it's hard to fit under some of my fitted sheets. Thank you. It's Cinvoice mattress wedge!

Arrived damaged
Item works as it should, gives just enough lift. It was folded and wrapped extremely tight to fit in a small box, therefore had a 12” rip when unwrapped. No way to get it back in box so I’m stuck with it.

A giant sponge
It’s just one giant sponge. It was a little bit difficult setting it up because it is slightly larger than my mattress but it was easy to cut with my big chefs knife. Make sure the blade is very sharp.

Very good for those of us that require a sloped bed
Very comfortable solution to help after surgery.

Cut the straps before cutting the plastic wrapping
2 things: First - when up wrapping, look for a strap on each end and cut these so they don’t cut into the foam and rip it. Second, after the straps are cut, just peel back the plastic wrapping and orientate the foam so it can unroll on its on. Additionally you can plan poorly, don’t cut the straps and have a torn foam wedge. PS: it’s good to let the foam breath for a couple days, flipping ever 12 hours etc

Handy
I get positional, vertigo so this helps to prop a bit rather than having umpteen pillows.
