Assembling a Chest of Drawers — Assembly Instructions & Tips

August 2, 2026

The professional assembly of a chest of drawers requires systematically sorting all components, correctly handling connecting fittings, and essential wall anchoring to prevent tipping.

Anyone assembling furniture independently is often confronted with a multitude of screws, panels, and fittings. A structured approach saves both time and stress. Whether you are planning a classic bedroom chest of drawers, assembling a slim model with a 30 cm depth for the hallway, or putting together a wide variant with a 100 cm width for the living room – the fundamental mechanical principles remain identical. This guide leads you through the entire assembly process, from preparation to the final adjustment of the drawers.

Introduction and Checking the Scope of Delivery

Before reaching for your tools, you must check the contents of the delivery. Unpack the boxes lying flat on the floor. Use the cardboard directly as an underlay to prevent scratches on the furniture panels or flooring.

Modern cabinet furniture typically consists of coated chipboard or MDF. Check against the enclosed instructions whether all components are present. These include:

Side panels, base, and top panel (the carcass)
Back panel (usually made of thin hardboard)
Drawer fronts, sides, and bases
A bag of fittings (screws, dowels, runners, handles)

Keep the fittings strictly separated. Confusing screws with a 3.5 mm and 4 mm diameter can later cause the chipboard to split or runners to sit out of alignment.

Required Tools and Preparation

For smooth assembly, you need a solid basic set of tools. The following items should be ready:

Cordless screwdriver: With adjustable torque to prevent stripping the screw holes.
Screwdriver: Hand tools are indispensable for fine adjustments. Ensure you use the correct bits. Furniture assembly screws mostly use cross-recess heads, where a strict distinction must be made between PZ (Pozidriv) and PH (Phillips). The wrong bit will damage the screw head.
Rubber mallet or wooden mallet: For gently tapping in wooden dowels.
Folding rule and spirit level: For alignment and checking right angles.
Pencil: For markings during wall mounting.

Assembly resembles clockwork – a misplaced gear or incorrectly fitted runner will block the entire system. Take your time during preparation.

Step-by-Step Assembly

The exact sequence may vary slightly depending on the manufacturer, but the basic logic of carcass assembly is standardised.

1. Installing Carcass Runners

A common mistake is assembling the carcass first and then trying to screw the drawer runners into the narrow interior. Always fit the carcass runners flat on the inside faces of the side panels. Pay attention to the running direction of the roller runner or ball bearing runner. The rollers or stop must face towards the front edge of the unit.

2. Inserting Wooden Dowels and Connecting Fittings

Insert the wooden dowels into the designated end holes. A drop of wood glue enhances stability, but is not strictly necessary with purely mechanical connectors. Screw the cam dowel pins of the cam lock fittings into the pre-drilled threads or holes (usually 5 mm diameter). The round cam housings are pressed into the large holes (usually 15 mm) of the matching panels. The arrow on the housing must point towards the edge of the panel where the pin enters.

3. Assembling the Carcass

Join the base panel and the side panels together. Once the pins are inside the cam housings, turn them clockwise with a manual screwdriver by roughly 180° until they noticeably tighten. This pulls the components flush against each other. Next, fit the top panel in the same way.

4. Attaching the Back Panel and Checking Angles

The back panel gives the chest of drawers its structural stability. Before securing it with the enclosed nails (usually spaced 10 cm to 15 cm apart), the carcass must be squared. Measure diagonally from the top left to the bottom right corner with your folding rule and compare the measurement to the opposite diagonal. The carcass is truly square only when both measurements are millimetre-identical. Only then should you nail or screw the back panel firmly in place.

5. Assembling the Drawers

Drawer assembly is typically carried out using smaller cam lock fittings or standard chipboard screws.

Assemble the frame (front, sides, back).
Slide the drawer base into the designated groove.
Screw the runner components onto the bottom outer edges of the drawers.

When assembling an extensive chest of 8 drawers, batch production is recommended: carry out each step (e.g. inserting dowels) across all eight drawers before moving to the next stage. This saves a great deal of time.

6. Inserting the Drawers

Insert the drawers into the carcass from bottom to top. With a roller runner, the drawer is placed onto the carcass runner slightly tilted from above and pushed in. With a full extension ball bearing runner, the tracks usually need to be aligned precisely and pushed together until they audibly click into place.

Wall Mounting and Anti-Tip Protection

A fully assembled chest of drawers, particularly when all drawers are full and opened simultaneously, develops significant forward leverage. Wall mounting is not an optional step; it is an essential safety precaution.

Use the supplied mounting brackets. The fixings for the wall (plugs and screws) are often not included, as they must be matched precisely to the construction of your wall.

Masonry/concrete: Standard expansion wall plugs (8 mm) with matching screws (e.g. 5 mm x 60 mm).
Plasterboard/stud walls: Use dedicated cavity fixings or plasterboard plugs, as standard wall plugs will tear out immediately under tension.

Tips and Common Pitfalls

Uneven gaps: If drawer fronts hang crookedly or rub against each other, the chest of drawers is usually not level. Check the alignment with a spirit level. Placing a thin wooden shim under a foot is often sufficient.
Stripped screws: Setting the torque too high on your cordless screwdriver will strip the soft material of the chipboard. The screw will no longer hold. Always use a manual screwdriver for the final millimetres.
Incorrect runner position: Pay meticulous attention to the hole numbering in the assembly manual. An offset of just a single row of holes (often drilled in the System 32 grid) will cause the drawer to jam or sit skew.

Frequently Asked Questions (FAQ)

How long does it take to assemble a chest of drawers? For a compact chest of drawers 60 cm wide with three to four drawers, one person requires roughly 1 to 1.5 hours. For larger models with many drawers, you should plan for 2 to 3 hours.

Can I omit the back panel to feed cables through? No. The back panel is a load-bearing structural component. Without it, the carcass will collapse sideways under load. If you need to route cables, drill a clean hole into the fixed back panel using a Forstner bit (e.g. 35 mm or 50 mm diameter).

What is the difference between full extension and partial extension? A partial extension runner pulls out to approximately 75% of the carcass depth. The rear section of the drawer remains inside the unit. A full extension runner allows the drawer to extend 100%, granting unrestricted access right to the back corner.

Suitable Options for Your Project

Construction methods remain identical across most cabinet furniture, yet the aesthetic finish defines the character of the room. A simple white chest of drawers blends subtly into bright spaces, whereas a black chest of drawers creates strong contrasts. Those who favour natural textures often opt for a wooden chest of drawers with distinct grain patterns. Colour accents are equally popular: a grey chest of drawers offers a modern, neutral balance for home offices or bedrooms. Regardless of the decor, precise and square installation ultimately determines how sturdy and durable your furniture hardware and units will remain throughout everyday use.
