How to assemble a metal bed frame

Metal bed frames go together with a handful of bolts, but they are prone to squeaks and wobble if the joints are not tightened evenly. A little care with washers and the order of tightening makes a big difference.

Tools needed

  • Allen key (supplied)
  • Spanner (often supplied)
  • Rubber mallet
  • Cloth to protect the floor

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.

  • Head and foot ends
  • Side rails
  • Centre rail and support legs
  • Slats or metal cross bars
  • Bolts, nuts, washers and plastic caps

Step by step

  1. Step 1: Lay a cloth or the flattened box on the floor so the metal feet do not scratch it.

  2. Step 2: Bolt the side rails to the head end with washers under both the bolt heads and the nuts, finger-tight.

  3. Step 3: Bolt the foot end to the other ends of the side rails.

  4. Step 4: Fit the centre rail and screw the support feet down until they touch the floor.

  5. Step 5: Tighten all the bolts in a cross pattern, a little at a time, so the frame pulls square.

  6. Step 6: Fit the slats or cross bars and any plastic end caps.

  7. Step 7: Push on each corner to check for wobble and squeaks, and tighten any joint that moves.

Common mistakes

  • Leaving out washers, which makes metal joints squeak and loosen.
  • Tightening one corner fully before the others, which twists the frame.
  • Forgetting the plastic caps on the feet and tube ends, which leaves sharp edges.

Safety notes

  • Wear gloves; cut tube ends can be sharp.
  • Keep fingers out of the joints when a helper is lining up a heavy end.

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.
