Putting two twin beds together is convenient, thanks to this mattress accessory from Stack and Stack.

Create a luxurious king size bed with the Create-A-King. Just slide two mattresses together, place the soft poly sheepskin along the middle, adjust the belt to fit the length of the mattresses, and tighten! You will instantly have the size and comfort of a king size bed made out of your existing twin mattresses. Easy to use and machine washable! Adjustable snap-shut belting assures mattresses will never separate during the night.

The product may be cared for by machine washing and fits mattresses which are at least 80″ long.
