Foosball tables are heavy and the steel player rods stick out on both sides, which makes them awkward and easy to bend in a doorway. Most do not disassemble much, so the job is about protecting the rods and lifting the dead weight.
Pro tip: Removing the legs is the single best move, since it protects them and shrinks the load.
Watch out: Never lift a foosball table by the player rods, since they bend easily and are hard to replace.
