Most adjustable beds use two separate mattresses on two separate bases. Each side can raise and lower independently. It is great for comfort. But it creates a gap that is harder to fix than on any other bed type.

The challenge is movement. On a regular flat bed, the mattresses sit still. On an adjustable bed, they constantly change angle. Any gap filler needs to handle that movement without popping out, shifting, or bunching up.

• Foam wedges pop out when you raise the head or foot. They are designed for flat beds.
• Toppers cannot flex when each side adjusts independently. They bunch up and pull off. See our article on toppers over two mattresses.
• Fitted sheets cannot hold mattresses that move in different directions. The elastic gives way.
• Tape or DIY straps restrict the base movement and can damage the mattress fabric.

The common thread? These solutions were designed for static, flat beds. Adjustable beds need something built for movement.

The Bedbinder Deluxe is a horizontal bed bridge. It wraps around both mattresses from underneath. Here is why it is the ideal solution for adjustable beds:

• Flexes with the base. When you raise the head or foot, the Bedbinder moves with the mattress. It does not pop out or shift.
• Keeps mattresses locked together. The gap cannot form. The mattresses cannot slide apart on the adjustable base.
• Independent adjustability. Each side still raises and lowers on its own. The Bedbinder does not restrict the base.
• Nothing on the surface. No bump, no ridge, no foam between the mattresses.
• Works on all adjustable brands. Whether you have a Sleep Number, Tempur-Pedic, or any other adjustable bed.

Setting up the Bedbinder on an adjustable bed is easy:

1. Lower both sides of the adjustable base to the flat position
2. Push both mattresses together so they touch
3. Lay the Bedbinder flat across the center of both mattresses
4. Pull the straps down the sides and click the buckles underneath

Now test it. Raise one side. Raise the other. The Bedbinder flexes naturally with each mattress. Both sides move independently. The gap stays closed.

The whole setup takes less than a minute. No tools needed. See our step-by-step installation guide for more details.

The Bedbinder is compatible with every adjustable bed setup:

• Split king adjustable: Two twin XL mattresses on separate adjustable bases. The most common setup. See our split king guide.
• Motorized boxspring: Boxspring beds with built-in motors. The Bedbinder wraps around the top mattresses.
• Hospital-style adjustable: Beds with head and foot adjustment. Works perfectly with the Bedbinder.
• Zero-gravity bases: Bases that elevate both head and feet. The Bedbinder flexes in all positions.

No matter what adjustable bed you have, the Bedbinder keeps both mattresses together while allowing full range of movement.
