I took Ana's awesome queen-sized storage bed plans and jut made a couple minor tweaks for my full. Our bedroom is TINY, so I wanted queen (or king) sized drawers/cubbies, which means I kept 20" depth. The side boxes run 53" in length, 54" for the end. I used poplar ply for the boxes, red oak for the trim, and I stained everything with a Varathane Early American wood stain, followed by a couple coats of polycrylic. It came out beautifully, and I love how easy it is to move around and set up.
For the final step, I'm still debating adding drawers or doors, which would hinge on the bottom and secure with cabinet magnets. I'm leaning toward the latter just because our bedroom is so small it will make accessibility a bit easier.
