How to assemble dining chairs

Boxed dining chairs usually arrive as a back frame, a front leg frame, side rails and a seat. Build all the chairs side by side, tighten evenly, and they will stay quiet and solid for years.

Tools needed

  • Allen key (supplied)
  • Cross-head screwdriver
  • Soft cloth or rug to work on

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.

  • Back with rear legs
  • Front legs or front frame
  • Side rails
  • Seat pad
  • Bolts, curved washers and seat screws

Step by step

  1. Step 1: Unpack all the chairs at once and sort the parts into one pile per chair, so the bolts do not get mixed up.

  2. Step 2: Lay the back frame flat on a soft surface with the bolt holes facing up.

  3. Step 3: Push the side rails onto the back frame's dowels and fit their bolts with the curved washers, only finger-tight.

  4. Step 4: Fit the front legs to the other end of the side rails the same way.

  5. Step 5: Stand the chair on a flat floor and press down on the seat frame so all four feet touch.

  6. Step 6: Tighten the bolts diagonally, a little at a time, until they are firm.

  7. Step 7: Place the seat pad on the frame, line up the holes from underneath and fix it with its screws.

  8. Step 8: Sit on the chair, rock gently and re-tighten any bolt that moved.

Common mistakes

  • Tightening bolts fully while the chair is lying down, so one leg ends up short.
  • Mixing up bolts of different lengths, so a long bolt pierces the seat or a short one barely grips.
  • Leaving out the curved washers, which spread the load around the bolt.

Safety notes

  • Check the bolts again after a couple of weeks; a loose chair can collapse when someone leans back.
  • Do not stand on dining chairs to reach high places.

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.
