    • It stays in place even when the beds aren't aligned!
Size: 75" L x 10" W
I use this on my adjustable bed and it fits perfectly. It actually works well when the two mattresses are in different positions too. I am very impressed with the usefulness of the gap filler. It is very easy to install, just let it relax while you get the bed ready and place it into the gap. No problems at all. It comes with a cover that can be removed and washed (I plan to use the gentle cycle for this to make sure it isn't torn up by other items in the washer), so it should be clean and last a long time. ... show more

    • Perfect for adjustable beds
This is a much needed addition to our bed. We have a split king adjustable bed. Our dog was constantly slipping in between the two beds. This closed that gap & she now sleeps in between the beds comfortably. Works well on closing the gaps in between the sides even when we sleep at different levels. Great value for the money. It was easy to install & very durable. ... show more

    • OK job
Size: 75" L x 10" W
This wedge filler does the job, however, the top layer could be made much thinner. As it is, it creates a thick bulge line between the beds which is not very attractive.

    • Solved the problem
Size: 80" L x 12" W
The gap in the middle of the split king was really annoying. Since the beds rise and fall differently the mattresses can't stay together. So I wondered if there was a solution on Amazon. This was it. Its T shaped and fits into the gap and its cushiony on the top so its comfortable now if you gravitate toward the middle of the beds. Cover unzips and washes easily with the sheets. I am very happy with the product and recommend it. The fast shipping was important so we could get a good nights sleep. It also moves easily when the mattresses adjust. ... show more

    • Space filler
Has definitely helped with filling the gap between our adjustable bed, but slides down the bed way too easily. Wish there was a better way to keep it in place on the bed.

    • Fills the Gap Perfectly!
Size: 80" L x 12" W
We recently purchased a split king adjustable bed. While we love having the option to sit up/lay down at different times we did find the gap a bit annoying. Mostly because our dog would fall down in it (she is very little). I found this gap filler and decided to give it a shot. IT IS PERFECT! It fits nicely completely taking away the gap and is flexible enough that when one of us sits the bed up it just moves with it and then back into place. I also love that it makes the bed look like 1 piece when I make it with our bedding. A great buy. Removable slip cover makes washing easy. I cannot recommend this enough. ... show more
