Six-piece section couch. Purchased a little over a year ago new from Nebraska Furniture Mart's clearance store. The only visible issue with it is slight fraying on the right end piece due to a roommate's cat.
You will need to be willing to move out the couch. I am on the fifth floor of an apartment building in downtown Omaha, but there is elevator access and always room to park outside the building's entrance.
The footrest piece is 36 inches by 36 inches.
Each end couch piece is 36 inches wide and 42 inches long.
The three interior couch pieces are each 36 inches by 36 inches.
