Fits perfectly. Really like how it can lay flat.

Pillow placement is a very important thing for me. Before buying this, I would have to wake up in the middle of the night to fix my pillows because it would fall in the little crack between my headboard and my mattress. However, now the problem is resolved and I can sleep continuously. The size that I bought is for a king but I have a queen and it still fits the Velcro pocket edition keeps my iPhone 13 pro while it’s on charge. I would love to give this a five stars but I can’t with good heart. Because about after A week of using this firmness didn’t hold. Before going to bed I have to reposition the gap filler which isn’t too troublesome for me. The filler is soft and comes with a removable washable cover. After positioning it once before bed the filler stays in place through the night. It is a nice quality and worth the money

I ordered this JXHLLA Triangle Bed Gap Filler in King size for our Captain's type storage bed with a connected bookcase and storage headboard. I thought this product was a unique design idea to keep our items on the shelves on our headboard from falling into the gap between the headboard and the mattress. I also thought that it might help keep the fitted sheet tighter and prevent the fitted sheet corners from coming off while sleeping. We have a Purple brand mattress that we love but the fitted sheets don't stay taught because of the rounded corners. This memory foam gap filler comes compressed in a tight roll but expanded completely within 1-2 hours. The shape and color are accurate to the pictures on listing. The quilted cover is soft and fits well. The shape is unique to make it versatile to use in different positions. The king size fit the width of our bed perfectly and the edges for tightly between the gaps with our bed. We are using it with the longest edge down and inserted in the gap so that there is more tension to keep the sheets tight. The height is minimal even using at the tallest angle, so it doesn't really make a significant difference to use for propping up pillows but would probably help keep the pillows from sliding down into the gap as long as the gap isn't too wide. The only negative we have found so far is that the zipper is right in the middle of the side that faces up for the way we are using it. So the zipper is obvious and not attractive and if you are someone that sleeps with their arm under pillow above your head, it might be annoying. This isn't a big deal for us because our pillows are covering the entire gap filler when bed is made and we do not sleep in that position. This bed gap filler is unique and made well using quality materials and useful for us in multiple ways.

We’ve needed a Bed Gap Filler for years but didn’t know they made one that would fit our king bed. Due to the design of our headboard posts, we always had a gap over 6 inches. We were constantly digging for remotes, pillows, books, dog toys and other items. This Triangle Bed Gap Filler fits perfectly and solved the problem. The gap filler arrived vacuum sealed in an approximate 16” x 8” package. It required just seconds to assume its original shape and be ready to install. As you can see in the photo, it filled the gap and created a smooth transition on the bed. After a few nights sleep it hasn’t shifted, fallen into the gap or curled up. The fabric cover is soft. In our Bo install the zipper is hidden and doesn’t create a problem. It’s good that it will zip off so the cover can be washed. We are very happy with this product. I only wish it had come with two attachable pockets as my wife claimed the one. It’s great for holding reading glasses or the remote.

It's better than nothing, but I would have liked it to be firmer.

This triangle gap filler has been a great addition to our bed setup. It slots perfectly into the space between the mattress and headboard, so we no longer have pillows, phones, or the remote sliding down and disappearing into the void every night. I use a box spring and it has raised the bed to a considerable level but there’s a big gap in which things fall down repeatedly. The foam has a nice balance of firmness and give . It easily holds its shape but still feels comfortable if you lean back against it while reading. Setup was simple, though it does take a couple of days to fully expand after unboxing. The vacuum seal compressed it completely and it required the time to fully expand. The cover is removable and washable, which is a nice touch for keeping it fresh long-term. Overall, a simple fix for an annoying problem, and well worth it if you’re tired of things vanishing into the gap.

Perfect fit! Love the optional ways can use it to fill the gap between the mattress and headboard. Relieved that I found this to help keep my baby from getting stuck in there! The little pocket that comes with it can be Velcro to either side to conveniently hold your remote or phone!

I really liked the idea behind this triangle pillow, and the color looks great on the bed. It arrived quickly, and the material feels nice and provides good support for sitting up in bed. It also does a decent job of helping keep regular pillows propped up. However, I was hoping it would completely prevent pillows from sliding into the gap between the mattress and the headboard. Unfortunately, the wedge itself tends to shift into the gap as well, so it doesn't fully solve that problem in my experience. Overall, it's a nice-looking product that shipped quickly and offers extra support while sitting in bed, but it may not completely eliminate the issue of pillows slipping into the crack.
