Flat-pack assembly: cam locks, torque discipline and the anti-tip rule
Furniture assembly looks unskilled until you have watched someone do it badly. The core skill is torque discipline: most flat-pack furniture is MDF or particleboard, and the cam-lock and confirmat fittings that hold it together strip the moment they are overtightened. A pro runs a drill-driver with the clutch set low for speed, then finishes every fitting by hand. The second skill is sequence, reading the exploded diagram once, sorting fittings into trays, and building sub-assemblies flat on the floor protected by the packaging cardboard rather than on bare tile.
Realistic times matter for planning your visit: a standard double bed frame takes 60-90 minutes; a chest of drawers with runners, about an hour; a large multi-door wardrobe is a two-to-four-hour job and genuinely needs two people to lift the carcass upright without racking it out of square. If a vendor quotes a six-door sliding wardrobe as a one-hour solo job, the quote is wrong and the wardrobe will show it.
