Remember, it was still August - the sun was beating down on them, tshirts soaked in the first 5 minutes. Once in the building, they had to bring everything up to the 6th or 5th floors in 2 tiny elevators (they fit about 4 people, 6 uncomfortably) without A/C.
Mid afternoon a lift arrived in the back parking lot. They loaded our king mattress on it and mechanically elevated it to the 5th floor balcony where they took it in through the sliding glass doors. They also brought up one set of shelves this way. But that's it. Two items! All the rest came by cart, elevator, and heavy lifting.
They got it all in before 4pm, then spent an additional hour re-building our beds, dining room table, coffee table, and desks.
