With the help of another person, remove the top bunk from the lower bunk.
Note: Switching the headboards will allow the two single beds to be identical (the headboards will have
taller posts and the footboards will have the shorter posts).
CONVERTING THE BUNK BED INTO TWO SINGLE BEDS
Remove the ladder and all the guardrails.
Disassemble the side rails from all headboards (top and lower bunks).
Re-assemble the headboards (with tall posts) and footboards (with short posts) to side rails.
