Flat-pack furniture is everywhere in Greek homes, Airbnb apartments, and hotel rooms — affordable, easy to ship, and ready for any space. Yet a rushed assembly is the fastest way to end up with a wobbly wardrobe or a chest of drawers that will not close. The video above walks through the ten most important techniques, and this article turns them into a clear, ordered process you can follow start to finish.
Why Getting Assembly Right Matters
In a holiday rental or hotel room, furniture that squeaks, leans, or loses a door creates bad reviews and early replacement costs. A correctly assembled piece — joints fully seated, dowels straight, cam locks tightened in the right sequence — will last years without any maintenance. Taking an extra thirty minutes the first time saves hours of remedial work later.
For owners managing multiple properties across Greece, a repeatable process also means you can brief a helper or a local handyperson with confidence, knowing the result will be consistent every time.
What You Need Before You Begin
Most flat-pack boxes include a small Allen key and sometimes a basic screwdriver. These tools are functional but slow. A cordless drill with a Phillips-head bit and a correct-size Allen bit will cut assembly time significantly without risking over-tightening. You will also want a clean, padded surface to lay panels on — a flattened cardboard box from the packaging is ideal — plus a small bowl or tray to hold loose fixings so nothing rolls away.
How to Assemble Flat-Pack Furniture: 5 Key Steps
- 1
Unpack Everything and Check the Parts List
Open all packaging and lay every panel, fitting, and bag of hardware on a clean floor or table. Match each piece against the parts diagram in the instructions before driving a single screw. Missing a cam lock or a dowel at this stage is far easier to fix than discovering it halfway through assembly. Count the hardware by type and set it in a segmented tray or separate small bags so you can grab exactly what you need at each step.

Read the Full Instruction Sequence First
Skim the entire instruction sheet from start to finish before you begin. Flat-pack instructions are designed to be followed in exact order — panels that look interchangeable often have pre-drilled holes on one face only, and fitting them the wrong way means you cannot insert a cam lock later without disassembling. Understanding the full picture takes two minutes and prevents the most common assembly mistakes.

Pre-Insert All Dowels and Cam Locks Before Joining Panels
Drive dowels lightly into all pre-drilled holes, and drop cam lock nuts into their circular recesses before you try to connect any panels together. When you are joining two large panels, it is almost impossible to load these fixings once you are holding pieces together. Working on a flat surface, pre-load every fitting, then align and press the panels together firmly so all dowels seat at once.

Join and Tighten in the Correct Sequence
Start with the base or back panel as an anchor, then attach side panels, and leave the top or face frame until last. Tighten cam locks with a flat-head screwdriver to about 180 degrees — they click or firm up noticeably when fully engaged. Do not over-rotate or you will crack the cam lock housing. Work around the piece systematically: snug all fixings first, then go back and give each a final quarter-turn to equalise the clamping force across joints.
- 5
Check for Square, Then Attach the Back Panel
Before fixing the back panel, stand the carcass upright and measure diagonally from corner to corner. If the two measurements differ by more than a centimetre, push one corner gently until they match — the structure is still flexible at this stage. Attaching the back panel while the carcass is square locks that shape permanently. Use the small staples or screws provided and work from the centre outward to avoid bowing the panel.

FAQ
- Can I assemble flat-pack furniture alone or do I need a second person?
- Most shelving units, desks, and small wardrobes can be assembled solo if you work on the floor rather than upright. Large wardrobes with tall side panels genuinely need two people for the moment you tilt the carcass vertical and attach the top panel. For anything taller than 200 cm, plan for a helper at that stage even if you handle the rest alone.
- What is the most common mistake that leads to a wobbly or misaligned result?
- Tightening screws and cam locks too early — before all panels are joined and properly aligned — is the leading cause of misaligned furniture. Fixings that are snugged down while panels are still slightly out of position lock the error in place. The rule is: get every piece loosely connected and check for square first, then go around and tighten everything fully.
- Is it safe to use an electric drill instead of the Allen key that comes in the box?
- Yes, with two cautions. Use a torque-limited setting (most cordless drills have a numbered clutch ring) so you do not strip the cam lock housing or snap a dowel. Also, hex (Allen) bits are available in the same sizes as the included key — typically 4 mm or 5 mm — and make drill use practical. Avoid high-speed driving into cam locks; seat them by hand for the last half-turn.
