How to assemble a wooden bed frame
A wooden bed frame is a headboard, a footboard, two side rails and a slat base. The side rails usually join the ends with long bolts and barrel nuts or with hook-in brackets, and the centre rail stops the slats from sagging.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Headboard and footboard
- Two side rails and a centre rail
- Centre support legs
- Slats, slat holders or a slat roll
- Bolts, barrel nuts or corner brackets
Step by step
Step 1: Build in the bedroom, with enough room to walk around the bed on all sides.
Step 2: Screw the slat ledges (the thin strips the slats rest on) to the inside of the side rails, if they are not already fitted.
Step 3: With your helper holding the headboard upright, fix both side rails to it with the bolts and barrel nuts, finger-tight.
Step 4: Fix the footboard to the other ends of the side rails the same way.
Step 5: Fit the centre rail between headboard and footboard and screw the support legs down so they just touch the floor.
Step 6: Check the frame is square by measuring the diagonals, then tighten all bolts firmly.
Step 7: Lay the slats evenly across the frame, fixing them into their holders or screwing the ends if the manual says so.
Step 8: Put the mattress on and check for creaks; a creak usually means a bolt that needs another quarter turn.
Common mistakes
- Leaving the centre support legs short of the floor, so the slats bow in the middle.
- Spacing slats more widely than the manual allows, which can void a mattress warranty.
- Over-tightening bolts into soft wood so the barrel nut pulls through.
Safety notes
- Carry headboards with two people; they are heavy and awkward.
- Keep the bolts and small parts away from children during assembly.
