Stairs replace the ladder and each step is a drawer - three compartments from 11.5 to 23.5 in wide - so the climb up doubles as the storage a child's room usually lacks. Steps measure 14 x 14.5 in with rises of 12 and 13 in, rated 200 lbs like the beds themselves. Between the bunks there is 31 in and guardrails stand 12.5 in. The footprint runs 94.5 x 42 in, longer than a standard bunk because of the staircase. Pine, plywood and engineered wood weigh 147.5 lbs across 2 cartons.
