Help with Taylor King Sizing and Entry Way

[LincolnParker]

I have been reading all the helpful information on this site (thank you) and have decided to go with a fabric TK sectional if we can get it to fit. We live in a narrow 100 year old home in Chicago and need help with sizing (i) for the floorplan; and (ii) to ensure we can get it though the door before ordering remotely.

SIZING FOR ROOM: For the floor plan we need help deciding between 2 pieces (return) and 3 pieces (corner). Given the room is narrow I was thinking of staying below 40" depth so TKTM Standard or TK Cozy Creations with track arm and unattached pillos. Room Dimensions are:
172 inches - Length of sectional window wall (N) from perpendicular sectional wall (E) to first stair up. 54 inches stairs to first window.
149 inches - Length of stair wall (W) from all to entry closet to sectional window wall (N).
309 inches - Total length of East sectional wall.

SIZING FOR ENTRY: Living room is on second floor of home so we have 2 options to bring the pieces up.
Rear Stairs: Open back staircase to double french door entry to kitchen. Doorway between kitchen and living room is 30.5”w x 83” tall.
Front Stairs: Double door entry to 38”W staircase (37” at widow frame). Landing in front of entry is 43”W and 102” tall. Door way into living room is 35.5”W and 83” tall.
The sectional pieces are listed at 38” tall however I am not sure if that includes the removable pills or if legs can be removed.

I can also attached pictures. Any assistance is very appreciated!
