ENITYASplit King Gap Filler for Adjustable Bed, Twin to King Converter with Removable Washable Cover, Twin Mattress Connector for Guest Stayover/Family Room/Vacation Rentals(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.

A real no-brainer. Fits between the mattresses perfectly - stays in place and is comfortable to sleep on. I was concerned about the "hump" (that it would be noticeable sleeping on it), but it's very soft and pliable.

Works good! Wish I could get it in other colors. Doesn’t move much and is comfy. Makes our split bed more comfortable for the dogs and kid lol.

This item stays in place! It is very soft and comfortable! It has a cover that you can remove for washing! I am very impressed with it! I am so glad I bought it! Love, love, love it!

UPDATE: 3-19-2025MY ERROR RE THIS PRODUCT. My wife ordered two different brands (by mistake) and the first one arrived which was terrible and we returned for credit. we were thinking it was the only one she had ordered but after 3 days this one arrived so we were both wrong. This product is well made and fits exactly as described. We installed it...bought a King sized single bed spread to cover it and slept on it last night on our Sleep Number double-bed-put-together. All good. I highly recommend this Brand! That's why i stated the one I received looked nothing like the other one which is this one. My bad.... Sorry!MY MISTAKE: What a waste of time and money. This product was not designed to fit and will not stay put on the corners. Try as I may it refused to attached to the corner ans hold. My wife and I fought this battle and decided it was a bad product. Frustrating!NOTE: The photo shown looks nothing like the item received.

Fits nice but it is a little hard.

Why did you pick this product vs others?:Love that this has a washable cover. I washed a couple of times & it held up fine. I have a cal-king split bed & I place this between the 2 mattresses. It works well. The previous one I bought from another company didn’t have the cover so I had to throw out as it became dirty.

Just got it but very happy how it fills the gap. Comfortable and we don't even know it's there!
