Would this sectional fit in my great room which is 18' x 16'? Would the love seat sectional be a better fit? Ceiling is 14'. The long section would back to a wall of windows and correspond to the 18' width, though would have to allow for hearth on one side that is 2' wide plus walking space at least on the hearth side. Is 2' feet enough walking space and should it be on both sides? The tv wall mount on the opposite wall from the window wall. If floated, how much space is needed from the window wall? Seems if went with the larger sectional wouldn't allow for any other seating.
