My older two boys share a room and sleep in bunk beds. Since we moved them to bunk beds it's been great as it has opened up a ton of space in their room for quiet time away from the chaos of the rest of the house. I love bunk beds.
Recreate this. Buy 2 tall skinny dressers & wall shelf, place the wall shelf in the middle at the same height of the tall dressers. Push bed up to all of this and you have the greatest hidden storage that insn't in a wall space.
