Dimensions, access, moving parts and protection: four points to check before pickup.
For large furniture, do not only measure the item. Doors, stairs, corridors and lifts may be the limiting factor.
Drawers, doors, shelves and other loose parts should be emptied, removed or secured so they do not move unexpectedly while carrying.
Edges, glass, painted surfaces and delicate fittings deserve special attention. Special protection requirements should be stated in advance.
