Short answer
Empty it, take out doors, drawers and shelves, then remove the back panel before slackening a single cam. Turn every cam a half turn anticlockwise, then ease the panels apart by hand — never lever or hammer. Label every panel and bag the fittings per joint. Expect the unit to be perhaps 70 per cent as rigid next time.
Flat-pack is designed to go together once. It can be taken apart and rebuilt, but every cycle enlarges the holes slightly and every shortcut splits the board. The difference between a unit that rebuilds well and one that goes in a skip is almost entirely the order of operations and the refusal to force anything.
Safety
What you'll need
- Screwdriver, and the original hex key if you have it
- Masking tape and a marker for labelling
- Resealable bags for fittings
- Rubber mallet and a softwood block (optional)
- Pry bar or scraper with a wide blade, for the back panel (optional)
- Blanket or cardboard to work on (optional)
Step by step
- Empty it completely and take off the wall anchor last, not first.Everything out. Then doors off, drawers out, shelves out — the unit gets much lighter and much easier to control. Release the wall anchor only when the carcass is empty and someone is holding it.
- Photograph it from several angles before anything comes off.Hinge positions, shelf pin heights, which way the back sits, how the plinth attaches. Two minutes of photographs beats an hour of guessing later.
- Label every panel as it comes off.Masking tape and a marker: left side, top, base, and an arrow for which edge is up and which face is front. Chipboard panels look identical and are not — the holes are handed.
- Take the back panel off first.Pull the pins with pincers, or work a wide scraper under the edge and lift evenly. Never lever from one corner: hardboard tears. If the back is beyond saving, cut a new one on reassembly rather than trying to salvage a shredded sheet.
- Turn every cam a half turn anticlockwise.All of them, before separating anything. Panels forced apart with one cam still engaged tear the board out around the hole and that joint never works again.
- Separate panels by hand, straight out.Dowels come out along their own axis. Pull the panel straight away from its neighbour with even pressure at both ends. If it will not move, a cam is still engaged somewhere — go and find it rather than pulling harder.
- Persuade a stuck joint with a mallet and a block.A rubber mallet against a softwood block placed against the panel, tapping evenly. Never strike the board directly and never hit near an edge or a hole.
- Bag the fittings by joint or by step.Cams, bolts and dowels in labelled bags, taped to the panel they belong to. Loose fittings in one bag is how the rebuild becomes an afternoon of trial and error.
- Transport panels flat and face to face.Melamine scratches against itself, so put cardboard between faces. Panels carried on edge in a car crack at the corners.
- Expect a weaker unit and plan for it.Holes wear. On reassembly, expect to glue the dowels, fit a new back panel with screws at close centres, and re-anchor to the wall. A second build is the right moment to upgrade the back.
Tips
- Dowels usually stay in one panel and shear off in the other. Buy a bag of 8mm dowels before you start — they are pennies and a snapped one is otherwise a stopped job.
- If the unit is going straight to a new home, dismantle it into the largest sub-assemblies that will fit through the doors, rather than into individual panels. Fewer cycles, less wear.
- Wide flat panels are the part that breaks in transit. Sandwich them between two sheets of cardboard and keep them vertical against a seat back, not flat under other loads.
Common mistakes
- Levering panels apart before all the cams are released — The cam is still gripping the bolt. Force goes straight into the chipboard around the hole and blows it out.
- Dismantling a loaded or wall-anchored unit — It becomes unstable as soon as the first joint is slack, and a tall carcass with contents can fall on someone.
- Prising the back panel from one corner — Hardboard tears along the pin line. Lift evenly along an edge, or accept a new back on reassembly.
- Not labelling panels — Chipboard panels are handed and the hole patterns are subtly different. An unlabelled pile is a rebuild by trial and error, and every trial enlarges a hole.
If it doesn't work
A dowel has snapped off inside a hole
Cause: Dry, tight joint pulled apart under strain — Fix: Drill it out carefully with an 8mm bit, or pull it with pliers. Fit a fresh dowel on reassembly and glue it.
The board has blown out around a cam hole
Cause: Panel forced apart with the cam still engaged — Fix: Plug with a hardwood dowel and glue, cure, re-drill at 15mm. See the chipboard repair guide.
The rebuilt unit is noticeably floppier
Cause: Normal — the holes have worn — Fix: Glue the dowels, fit a new 6mm back panel with screws at close centres, and anchor to the wall.
Questions people ask
How many times can flat-pack furniture be taken apart?
Realistically once or twice before the joints are noticeably loose. Each cycle wears the dowel holes and the cam housings. By the third rebuild most units need glued dowels and a new back panel to feel solid.
Do I need the original instructions to rebuild it?
It helps enormously and most manufacturers keep PDFs online against the article number. Failing that, your own photographs taken before dismantling are worth more than the instructions.
Is it worth dismantling a cheap unit for a house move?
Often not. If the piece was inexpensive and the joints are already loose, moving it assembled or replacing it is frequently the better answer. Dismantle the good pieces and the ones that will not fit through a door.
