Having worked for a furniture removal company try this:. measure the height of the door and width.Pick out one that is not as long as the height of the door and the height from the floor to the top of the arms is less than the width of the door.When you get it to the door get a blanket and put it on the ground outside,stand the settee on one end ,depending which way you have to turn it, when you start getting it through and slowly pull it through on the blanket feeding it round and bringing the back in last getting someone to steady it as you pull.If its taller than the door slope it back and get the bottom through first and let the top through after. Or you could possibly ‘three corner’ it ,two people ,one each end, lift from the bottom and lower the front down so it comes through with the front of the arms and the top of the back skimming the door frame,mind the casters on the frame and wall. Most settees will go through normal sized doors.This is if you cannot get it delivered by the supplier.
