How to create a king bed connector

Updated April 17, 2017

If you are trying to stretch your budget dollars, consider joining two twin-size mattresses to create the king-size bed you have always wanted. There are bed connectors on the market that convert two twin mattresses into one king-size bed, but you can create your own at a fraction of the price. In fact, creating your own king bed connector is better because you can control the quality of materials you use, as those in the kits are not always sturdy enough for your needs.

  1. Assemble the bed frame to accommodate the two twin box springs. Pliers may be needed to tighten any screws.

  2. Place both twin box springs on the bed frame and then position the twin bed mattresses on top.

  3. Wrap the ratcheting lashing strap around the perimeter of the beds; slide the end of the strap into the ratcheting mechanism and pull through.

  4. Ratchet the lever mechanism up and down, as this action will tighten the lashing strap around the bed. The tightened strap will keep the twin beds together and prevent sliding or separation.

  5. With the measuring tape, measure a 1 foot wide by 100 inch long piece of egg carton foam and cut out the piece with scissors.

  6. Position the foam lengthwise down the middle seam of the bed where the twin mattresses meet. Tuck the ends of the foam under the lashing strap holding the mattresses securely together.

  7. Make your bed with the king-size bedding.

  8. Tip

    Consider using 1-inch thick memory foam instead of egg carton foam for a longer-lasting bed seam cover. Top your "new" king-size bed with a 1-inch mattress topper for a more uniform sleeping surface. Make sure the ratcheting mechanism of the lashing strap is hidden behind the bed, away from view.


    Do not use a ratcheting lashing strap with any hooks or loops, are they are bulkier and may interfere with tucking in the bedding.
