Where a rope-wrapped sectional starts: a two-seat module, 75 inches wide, arm on the left, right side open to join a corner or armless unit. Depth is 34.5 inches, seat height 16.5, arms and back level at 29.5. Grey 01 Durarope over a black aluminum skeleton, consistent with every other unit in the modular set. Contract-program fabrics dress the cushions. Sixty-seven pounds. Draw the layout first, then count the left arms, right arms and corners it actually needs.
