Carry Tall Items High and Low
A tall dresser, filing cabinet or shelving unit is awkward to handle. Make it a two-person job. Tip the item backward at an angle and have one person carry the top while the other carries the bottom. This centers the weight and keeps the item from swinging out of control. Transporting the item up or down stairs is easier too, since the carrying angle will roughly match the slope of the stairs.
'Hook' Chairs Around Corners
Stand Couches on End
If you ever have to maneuver a couch down a hallway and through a door, you may find it almost impossible to carry it horizontally and make the turn into the room. Before you enter the hallway, place the couch on its end and slide it to the doorway. You'll almost always be able to hook it through the door. If it's a bit taller than the door opening, start the top away from the door and gain several inches of clearance.
