DIY Full-Size Storage Beds

Lay two 80-inch-long by 20-inch high and wide storage cubby units flat on the ground, with the cubbies facing outward and the backs of the cubby units facing each other.

Place two 20-by-20-by-20 inch storage cubes in between either end of the cubby units, forming a rectangle that is 60 inches across and 80 inches long. There will be an empty space on the inside of the rectangle, which will later have support planks attached across it.

Glue a piece of 5-inch-long 1-by-2 lumber to the top and bottom of the back side of each of the cubbies that abuts a storage cube. These are screw anchors. Glue a screw anchor to the top and bottom of the sides of the storage cubes, mirroring the position of the anchors inside the cubbies. There should be 16 anchors altogether.

Screw the cubby units and storage cubes together with two 2-inch screws driven through each screw anchor, to form the storage base for the full size bed.

Insert three lengths of 20-inch 1-by-3 lumber evenly spaced across the gap in the middle of the base, with the planks flush with the top of the base. Secure the support planks in place with an angle bracket on each end, driven with 5/8-inch screws into the backs of the cubby units and the underside of the support planks.

Lay two sheets of 1-inch-thick MDF measuring 30-by-80 inches on top of the cubby and cube bed base. The MDF should fit on top of the base and be flush with the edges all around. Secure the MDF to the base and the support planks with 2-inch screws driven every 6 to 8 inches, about 10 inches in from the perimeter. That way, when you place a mattress on top the screw holes will be hidden.

Place storage baskets into the cubby holes on the base so that your storage bed remains neat and tidy.
