Flat-pack furniture challenge

Anyone who has bought and tried to assemble bookshelves and cupboards in flat-pack form will know how the instructions often fail to convey how to approach the task.

While DIY buffs who fancy their carpentry skills will probably manage to put a ready-to-assemble wardrobe together, there are always anxious moments as you try to follow complex diagrams.

But flat-pack furniture makes a lot of sense from a manufacturer's point of view. It takes up less space in warehouses, it can be transported more easily than other furniture, and it can be sold at a cheaper price to consumers.
