Bed Bridge from B3

For two idle twin beds, you can simply convert this into one king size bed with a bed bridge — which literally connects two mattresses seamlessly, leaving no bumps and gaps. The bed bridge is made of hypo-allergenic polyurethane foam and sold for $14.99. Practical and comfortable.
