  • STOPS THE GAP AND THE SLIDE: The Bedbinder Deluxe is a split king mattress slide stopper and a gap filler in one. Bed straps for mattress pairs pull both halves together from underneath, so the crack never opens while you sleep.
  • BUILT FOR ADJUSTABLE BEDS: Foam pads pop out the moment you raise the head. This bed bridge for adjustable split king holds in every position, which is why it also works as a bed surround for adjustable beds.
  • TURNS TWO SINGLES INTO ONE: A twin bed connector to make a king, a bed bridge twin to king and a twin to king converter kit in one strap. Two twin bed connector straps, one solid king, no seam in the middle.
  • ONE MATTRESS CONNECTOR, EVERY SETUP: Works as a mattress connector twin to king and as a mattress connector for two twin XL beds. A 2 bed connector that fits platform frames, box springs and adjustable bases.
  • INSTALLS IN 60 SECONDS: Wrap the band under both mattresses, click three reinforced buckles, pull tight. No tools. Holds up to 550 kg. Joined by 100,000+ couples since 2018, made in the Netherlands.

    • Dogs don’t fall through the split anymore!
Size: S - M - L - XL
Split King gap filler for an adjustable base. Delivered Sept 2. Happy with it so far. The gap between the two sides is closed enough that the dogs don’t drop a paw through the crack anymore. That’s the whole reason we got it. Fits the split as shown. No install drama other than it's easier if your partner helps hold the mattress up while you feed it through or vice versa. Only a few nights in, so I can’t speak to long-term sag or shifting, but right now it stays put and does the job. ... show more

It took me a while to find this “Bed Bridge” but after trial and error I found just the perfect fit for a Split King Adjustable bed. I purchased (and returned) two other gap fillers that had long straps to go around the mattress. Didn’t work. Then I found this great item. It didn’t take much to fit it to our bed and in the end there is no more “falling into the gap”. The fabric is good quality and very soft. I thought that I would feel the edges of the filler but, you don’t even know it’s there. I purchased it even though there were some negative comments about the plastic clips breaking. It is NOT cheaply made. I did however have to purchase king sized sheets to fit over the gap filler. It works just fine, raising (adjusting) one size and not the other. Oh, and I also got a blue eye cover with a little storage bag as a bonus. Great invention, great quality. It’s a must have for adjustable beds. ... show more

    • Hard to install but worth it
Size: S - M - L - XL
We bought this for our king adjustable Sleep Number Bed so our dog wouldn’t get stuck in the gap between mattresses. It definitely takes care of that. We have it positioned 1’ above the foot of the mattresses. It was pretty difficult to install with all the magnets holding the mattresses to the lower frame. Took about 45 minutes and some ingenuity to get the straps attached. At first we put it on top of the two fitted sheets but then realized we would have to unfasten it to wash the sheets - not going to work at all. So having read here in comments that you could use a king fitted sheet on a split king adjustable bed we gave that a try although I couldn’t believe it was going to work. Bed bridge is under the king fitted sheet. And it does work. We don’t raise the mattress head to great heights so maybe that’s what lets it work. And we never raise the foot parts. So yay! It all worked out. Even at the top of the divide between mattresses the gap is now much smaller. Four stars instead of five only for difficulty of installation and instructions that could have been more detailed, perhaps even specific to adjustable beds. ... show more

    • From twin to king
Size: S - M - L - XL
Review Image by eman@USMC Retired
We purchased 2 twin xl mattresses with adjustable frames and needed something to keep them together and be able to raise each mattress individually. This bedbinder did the trick with no problem. I can raise my side and watch TV while my wife sleep in flat position. It keeps both matresses together without seeing a gap. Well, after 1 week the plastic clamp broke. Great idea, but cheap quality. Not worth the price. ... show more

    • Doesn’t work
Size: S - M - L - XL
Good concept, but the clasps do not hold. The strap slips almost immediately. The buckle for the strap is plastic, which maybe wouldn’t be a problem, but a better design would be a buckle with teeth to hold the strap from slipping.

    • No more gap!
We have a split king sleep number and we were tired of the gap. I have a pretty plush topper on mine, and my husband sleeps on his side without one. We kept our individual sheets on, put this thing on nice and tight, then put a king sheet over it. I noticed if it was too tight, you could feel the tension under the sheets, especially on my side where it’s much softer. Once we loosened the straps, it was able to sink with my body and I don’t feel the fabric under the sheet anymore. The best part is that we have no gap! We used to push our beds together literally every night, and my topper would also slide off to one side. Since we put this on, I haven’t had to adjust my topper because it keeps that in place, too. I saw other people say that the fabric was cheap and wears out. We’ve only had it for a few weeks, so I can’t speak to that, but I find it comfortable (I don’t notice it), and it definitely keeps the beds together. I recommend giving it a try. And if it does degrade over time, I’m sure we would have no problem buying another one at the price point. ... show more

    • Very good
Very comfortable and size is perfect. Very easy to use and it’s not too thick but just right with enough stability and firmness to hold up and not fold onto itself. Works great. Definitely recommend if you have a split bed.

I bought this for split queen and it was a little big, but adjustable enough to work. I love it. No more having the mattresses split apart.
