Although most bunk beds are naturally stable despite their unavoidable wobble, many parents prefer to take no chances when it comes to the safety of their children. Fortunately, anchoring a bunk bed to the wall is a 10-minute job that uses tools many people already have at home. Anchoring bunk beds is well within the abilities of even those who are brand new to home maintenance.
Use your stud finder to find a point where a strut or rail in the bunk bed frame crosses a wall stud.
Measure the width or diameter of the bunk bed component at that point.
Buy a C-bracket of a size that matches the measurement you took in Step 2.
Place the C-bracket over the bunk bed component so its screw holes line up with the wall stud.
Screw the C-bracket in place using your power drill with screwdriver bits. This is easier if you have a friend hold the bracket in place while you drill.
If your bunk bed is positioned so that one or more holes in the bracket can't line up with a stud, use a drywall anchor. This is a plastic cuff for your screw. Drill a hole in the wall, then drive in the anchor with a hammer. Finish by driving in a screw just as if there were a stud at that position.
