Design sketches of the Seam armchair — Sketch studies of the horseshoe arm loop: one continuous tube carries the oak backrest, so there are no posts between seat and back.

Side view of the Seam armchair — In profile the backrest floats above the seat. The gap between the two oak parts gives Seam its name.

Close-up of the oak backrest and bronze steel arm loop — Moulded oak plywood meets bronze powder-coated recycled steel. Every part comes apart, to be repaired or recycled.

Technical drawing of the Seam armchair — Preliminary dimensions: 580 × 560 × 790 mm, seat height 470 mm. Sled base for stability on any floor.

Seam prototype on a workshop bench — First prototype: raw steel frame with ground welds and the bare oak backrest clamped to the arm loop to test fit and comfort before finishing.

Seam armchair beside an oak table in a bright room — Made for meeting and dining rooms: contract strength with the warmth of a residential chair.

Two armless Seam chairs stacked — The armless version stacks. A recycled-plastic underside cover protects the upholstery, and the fabric comes off for cleaning or replacement.
