001 · The joint
One joint. Repeated.
The Coburn is one module repeated. Each seat is a hardwood frame joined at four visible tenons and bolted through with a single hex fixing.

002 · The promise
Add a seat in year five. It still fits.
Every module made after 2021 fits every module made since. Add a chaise, drop a seat, swap the legs — the sofa you own in ten years is the sofa you bought, plus or minus a module.

005 · Origin
TENON started because a two-seater stopped fitting. Not because it broke — because the room changed, and the sofa couldn't. We build seating from a single joint repeated: a bolted mortise and tenon you can see, reach, and undo with one hex key. Every module made after 2021 fits every module made since. That is the whole product.
006 · The Coburn
Bolted mortise and tenon. Six upholsteries, nine finishes, seven configurations.
