Effective, Great quality
Great product, fits to catch eye glasses, remote, etc. from falling behind top of couch and wall. Cover is a quality fabric. I just bought another to place between headboard of bed and mattress. Thank you for this product.

Fills the gaps as needed
I was pleased overall with this pillow. It does the job. I was a little underwhelmed at first for the price because it seems thinner than I expected. However after using it my pillow doesn’t sink behind the bed any longer and I can fairly comfortably sit up in bed and watch TV. I do think it is a little pricey but I would like buy it again.

It works for my purpose
The queen size fit my queen size bed perfectly. I do not have a headboard and my bed is up against the wall. I had a spider crawl up the wall right above my head and that was it for me so I was looking for something that would lay flush against the wall and I found it. I don't understand these negative reviews, sounds like these people need a bigger bed or they're not pushing their bed up against the wall. I'm so glad I found this and I didn't have to spend a fortune solving my problem. So between this product and peppermint oil no more insects crawling up my wall right behind my head. Now I can sleep better at night! Whew!

Exceptional quality for a mattress wedge
Soft zippered cover and closes this dense foam wedge that suited my purpose perfectly. My mattress was too far from the headboard and pillows slipped down in the space between the wall and the mattress. This was the perfect solution.. I highly recommend.

Too small for my gap
Honestly this thing falls through the gap so the gap needs to be less than about 4 inches or so. If you have a bigger gap you’re going to need a bigger gap filler. Disappointed. Otherwise it’s fine in the softness and support camp.

Wedge Fit Perfectly
I have a queen headboard that has side panels, and this wedge fit the space perfectly. I also like the size of it. I no longer lose my phone when before it kept falling between the headboard & mattress. I can prop pillows up for sitting and reading and it isn’t super obvious it’s there. At the same time, It’s big enough that it doesn’t get pushed into the gap between the mattress & headboard

Longer than anticipated! Had to cut the foam to size which is fine as could do it with scissors. Initially very effective and helped stop the gap but with time the foam just gets pushed in and down the gap so effectiveness is limited.

This works great. it fits a normal king sized bang on. It is soft and it keeps my hair and anything else from falling behind the bed. I was always worried about spiders crawling up my long hair while I slept especially when I would wake up and my hair had fallen behind the bed! I wish it was cheaper (as I do for everything) but I can't complain.

Works wonders!!

I purchased for a king size bed but it is too long. I will cut it to length though. It’s great as I like sleeping more upright.

I got this because some items would fall in the crack between my headboard and my mattress. My cat likes to bring toys, sox and whatnot on my bed, and there was constantly a treasure trove of things along my wall. This blocks that crack, and no more things fall in it! I wouldn't say that it's comfortable, it's too small to use it as a back rest or anything. I was impressed at how small the sealed package was, and didn't expect the wedge to be big enough. But it is.
