How to assemble a sideboard

A sideboard combines a long carcass, doors and usually drawers. Most problems come from a carcass that is slightly out of square, which shows up later as doors that do not line up and drawers that rub.

Tools needed

  • Allen key (supplied)
  • Cross-head screwdriver
  • Small hammer
  • Tape measure
  • Spirit level

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.

  • Carcass panels: top, bottom, sides and dividers
  • Back panel
  • Doors with hinges, drawer fronts and boxes
  • Drawer runners, shelf pins, cam locks and dowels
  • Handles and screws, anti-tip fitting

Step by step

  1. Step 1: Sort the panels and fittings by the letters or numbers in your manual before you start; sideboards have many similar-looking parts.

  2. Step 2: Fit the drawer runners and hinge plates to the side panels and dividers while they are still flat. It is much harder once the carcass is built.

  3. Step 3: Build the carcass lying on its back: bottom, sides and dividers first, then the top, locking each cam half a turn.

  4. Step 4: Measure the diagonals and square it up, then fix the back panel all the way around.

  5. Step 5: Build the drawers: sides into the front, then the back, slide the base panel into its groove, and fix the runners to the drawer sides.

  6. Step 6: Stand the sideboard up, push in the drawers and hang the doors.

  7. Step 7: Adjust the hinges so the gaps between the doors are even and the doors close flush.

  8. Step 8: Fit the handles, place the sideboard, level it and fix it to the wall if it is tall or has heavy drawers.

Common mistakes

  • Fitting drawer runners the wrong way round (left and right are often mirrored).
  • Building on an uneven floor and blaming the hinges when the doors do not line up.
  • Tightening handle screws so hard they crack the drawer front.

Safety notes

  • Open drawers move the weight forward; anchor tall or drawer-heavy sideboards to the wall.
  • Do not let children climb on open drawers or doors.

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.
