Bought a full size bed/desk similar to this one (minus all the awesome drawer space on the left-hand side of this one!) for our son a few years ago... and it would be GREAT - SOo stupendously GREAT.. IF our ceilings were, oh, say... 3-4' HIGHER! Measure before you buy, folks. He still fits up there okay - for now - but is also currently growing like, WHOA.
Curtains around the sleeping area provide a little more privacy if you don't have the height for a sleeping platform/loft, and can be as simple or ornate as you like. Here, the light curtains emphasise the bold colours and dark wood of the bed alcove.
