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.

Tools needed

  • Allen key (supplied)
  • Cross-head screwdriver
  • Rubber mallet
  • Tape measure

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

  1. Step 1: Build in the bedroom, with enough room to walk around the bed on all sides.

  2. 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.

  3. Step 3: With your helper holding the headboard upright, fix both side rails to it with the bolts and barrel nuts, finger-tight.

  4. Step 4: Fix the footboard to the other ends of the side rails the same way.

  5. Step 5: Fit the centre rail between headboard and footboard and screw the support legs down so they just touch the floor.

  6. Step 6: Check the frame is square by measuring the diagonals, then tighten all bolts firmly.

  7. Step 7: Lay the slats evenly across the frame, fixing them into their holders or screwing the ends if the manual says so.

  8. 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.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
