What is the Bedbinder Deluxe?
The Bedbinder Deluxe is a bed bridge: an 80 cm strap that connects two separate mattresses from underneath.
- The gap in the middle disappears, and the mattresses can no longer drift apart.
- Fitted in 60 seconds, no tools, invisible under the fitted sheet.
- $57.00, washable at 30 degrees, 7-year warranty on the buckles.
Unlike a foam wedge it does not fill the gap: it removes it.

“I was tired of my split king mattress constantly sliding apart, creating a canyon between the two mattresses. This has done the trick and I don't even feel it at night.” Amazon review, US
How long have you accepted that gap between your mattresses as normal?
Two separate mattresses. Every night they drift apart, every morning you push them back.
-
How many years has this bothered you?
Without really fixing it, because that's just how it is.
-
How often does it wake you up?
Because you're lying in the dip, or your partner rolls into it.
-
What does it do to your sleep, your back, and the two of you?
Each on your own side, with a gap in between.
What have you already tried against that gap?
Our customers tried everything, or simply pushed the mattresses back every morning.

A strap around the whole bed

A whole new king mattress

Why didn't they work? A bed gap filler fills or hides the gap, but nothing holds the mattresses together.
The Bedbinder does: it is a horizontal bed bridge, one wide band around both mattresses that pulls them together and keeps them there. No sliding, no gap, and you can't feel it.
How does that first morning feel, when your bed is still exactly the way you left it?
Which fix belongs to which problem?
Five types, always in the same order. Not by how well they work, but by how often people try them.
| Type | What it does | When it is enough | Read more |
|---|---|---|---|
| Foam gap filler | Fills the gap with foam | In a guest bed that is rarely used | the bed gap filler |
| Connector strap | Joins both mattresses from underneath | In daily use, the only one that fixes the cause | the mattress connector |
| Full-width topper | Hides the gap, does not close it | When only the look bothers you | a sliding topper |
| One large fitted sheet | Goes over the top, holds nothing | As a finish on top of a strap | two twins and their size |
| Non-slip pad | Adds grip under the mattress | When one mattress slides on its base | the non-slip pad |

Recognize this?
This is what customers say about their Bedbinder.
The gap made it horribly uncomfortable. This fixed it.
“Spent a small fortune on a latex split king bed. Well, the gap makes it horribly uncomfortable to sleep on. But this has fixed the issue. I'm so happy to have tried this.”
It works so well and you can't feel that it's there.
“I was hesitant to buy but I am glad I did. It works so well and you can't feel that it's there. No more falling in the crack.”
Easy to install, and I can't feel it at all.
“It was easy for me to install by myself. After I made the bed, I can't feel it at all under the mattress pad and sheet. I'm happy with the purchase.”

Frequently asked questions
Yes. It fits two mattresses of 70 to 100 cm (28 to 39 inches) wide each, so beds and boxsprings of 140 to 200 cm (55 to 79 inches). That covers two twins or twin XLs joined into a king. Works on foam, pocket spring, latex and hybrid mattresses, even if there is a small height difference between them.
No. With a fitted sheet or topper over it you can't feel it; customers call it invisible under the sheets. If you lie right on the seam without a topper, you may feel the spot slightly.
Yes, you can: lift the corner of each mattress briefly to pull the straps underneath. With two people it's easier, and you're done within 60 seconds.
A foam wedge or gap filler lies in the gap and fills it, but leaves a bump you can feel. It doesn't stop mattresses sliding apart, so you keep buying a new one. The Bedbinder is a bed bridge: it goes around both mattresses and physically connects them, once. No gap, no sliding, no bump, no repeat purchase.
The buckles have been renewed and made from stronger material. They're rounded nylon, deliberately not metal: sharp metal buckles tear holes in your mattress and sheets, nylon doesn't. Nylon can also go straight in the washing machine, and it's industrially strong, up to 550 kg (1,200 lbs). If a buckle ever does break, you get a new Bedbinder within 7 years.
Together is ideal. The Bedbinder keeps your mattresses and your topper in place, the topper makes the surface even. A topper on its own doesn't stop the sliding and sinks into the gap itself. Two ways: the band around mattresses and topper together, or around the mattresses only with the topper on top.
Yes, if only the head end moves. This size is made for fixed beds and for adjustable beds where just the head section rises. If both the head and foot ends move independently, this Bedbinder is not the right fit; contact us and we'll help you choose. A foam wedge pops loose on an adjustable bed; the Bedbinder works under the mattresses and stays put.
Yes. It pulls both mattresses tightly together, so the gap closes and stays closed. You no longer feel the gap and your mattresses no longer slide. Combined with a topper it's perfect: one even bed.
