Take Apart What You Can
When you're lugging a sofa through a doorway, remember: You can always make it a few inches smaller by removing the feet. The same principle applies to any piece of furniture you need to make sleeker or lighter: Take off any and all knobs, drawers, shelves, racks and legs.
Remove Your Door Stop Molding
Sometimes, an extra 1/2 in. is all it takes to get through a doorway. If removing the door doesn't open up enough space, pry off the door stop molding. That will give you another 3/4 in.
