Hi, we are looking to purchase a reclining sectional for our basement. The individual pieces will fit down our basement stairway bc the backs remove. However I am concerned about the corner piece where the backs are not removable (44” x 44” x 35”). Is there any way this will fit down my basement staircase if turned on an angle? The staircase is 36” wide but the doorway is 31” wide. Thanks!
