Why this room works.

A horizontal king turns a long wall into a low, wide panel, and this 13 by 12 foot bedroom lets it breathe. The cabinet measures 86 inches wide and 83 inches high, so it sits well under the 9 foot ceiling and leaves the rest of the 13 foot wall open. The 76 by 80 inch mattress folds down on the 269 dollar horizontal hardware kit, and about 61 inches remain clear at the foot of the bed.

Soft gray slab fronts and natural maple edging keep the panel quiet, with matte black pulls as the only dark line on the wall. There is no storage flanking the bed and nothing to dust on top, just one clean cabinet that opens into a full size bed for two. Fold it up in the morning and the room is a plain, open bedroom again, ready for whatever the day needs.

The built-in sits on the 13-foot wall. The dashed outline extends about 83 inches from the back wall, leaving roughly 61 inches at the foot of the bed. The built-ins are finished in soft gray, natural maple, and matte black. The 86-inch modern cabinet leaves the rest of the bedroom open when the bed is up. 13 x 12 ft room with a 9 ft ceiling.
