matress wedge

This simple solution holds two spring mattresses securely together when placed on the floor, allowing you to print out pairs or quadruples and use them to connect the mattresses. It has been verified to work effectively with IKEA's Sultan model, but it should fit a wide range of other models where the combined frame width in the middle measures between 75-85 mm.
