Simple Floating Bed Frame (Queen)

Build three identical 2x4 inner frames using 3" self-tapping screws, two per joint.

Attach the toekick base to two of the frames, flush to the front and side edges, mirrored to each other. Screw every 12" at a slight angle with 3" screws.

Attach the 1x10 siderails to the outside of the frame with glue and 1-1/4" brad nails — the siderail is NOT flush on the top edge, only on the other edges, which is what creates the floating gap. Prefinish (paint or stain) the toekick's front edge and the siderail's front and top edges before continuing.

Prefinish the front edge of the front 2x4. Attach the toekick base boards to the siderails with 3" screws. For extra support, cut and attach corner bracing inside the base frame.

Prefinish the front, top, and side edges of the footboard. Attach it to the siderails with 2" screws from the inside, being careful not to let screws poke through.

Place the remaining inner frame inside the bed and attach to the toekick base and the footboard. Build and attach the headboard legs, top, and plywood back panel.

Lay the slats across the inner frames and attach. Sand and finish any remaining unfinished surfaces.
