You do not need a workshop to assemble furniture. Six tools cover almost everything that comes in a box.
The essentials
Phillips and flat screwdrivers, a set of Allen keys, a rubber mallet, pliers and a tape measure. With these you can build ninety per cent of the furniture on sale.
The two that prevent damage
A spirit level and a drill-driver with torque control. The level catches misalignment before it gets locked into the frame. Low torque stops the screw stripping the board, which is the most expensive and most common mistake.
What not to use
A drill at full speed on chipboard, keys that are roughly the right size, and the bent Allen key from the box for the final tightening. They are fine to start with, not to finish with.
Set up the space
Packaging cardboard on the floor, parts in assembly order, screws in separate cups. Time spent here saves double later.
When it pays to delegate
Tall wardrobes, beds with slatted bases and wall-fixed units need two people and experience. In the OSCAR app you book assembly with a fixed price before you confirm.
