I'm moving from one unit to another, within the same building. The new unit is up one flight of stairs and across the hall. I have a king sized bed (does not break down, but it's only a basic frame and is lightweight, just awkward), king sized mattress, child's mattress, a couple of tall wooden book cases, large aquarium (75 gallon), aquarium stand, and a full sized couch. There is an elevator in the building but it is small and at least a few of the pieces will definitely need to go up the steps (couch and at least one bookshelf). We have a hand truck, although I'm not sure it will be helpful for the items remaining to move.
