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.

Wonderful product!
Perfect solution to the large gap we had between our bed topper on the mattress and the headboard!

It's decent
I use this at the foot of my bed because there's a gap between the bed and footboard and things kept falling down there. This blocks it better, though I'd prefer if it was as high as my bed. Overall it works well and was a decent value.

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.

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!

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

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.

Perfect to close gap between mattress and bed
I have struggled for years to fill the gap between my mattress and the headboard of my bed. While I was searching for a bolster pillow for a new daybed, I found this item. It has filled that gap perfectly and my pillow no longer falls through that gap. It also provides a slight lift at the head of the bed.

Not that effective for our bed
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.

Excellent Product!
Very pleased with this purchase. Never even knew it existed. Mattress on a wooden bedframe, the pillows would find a way to squish down between the headboard and the mattress and push the mattress forward. Had tried anti-slip mats under the mattress with no luck. This sits nicely in the space between the headboard and mattress when mattress is butted up against the headboard as far as it can. Blocks the pillows from squishing down perfectly.

Great for stopping things from falling behind your bed
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.

Too long
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.
