We love this vintage beech and plywood Rappelkiste bunk bed and desk (note the small closet paneled with chalkboard)—something to have a skilled carpenter recreate. Designed in 1975 by Luigi Colani for German company Elbro. For more ideas, see the ingenious Bed Cupboard from Netherlands-based Kids Factory and our 10 Easy Pieces: Kids' Modern Beds post.
