The Story Behind This Sofa
This piece is built to be restored rather than replaced, and that is a design decision made at the frame stage.
Everything that wears out on a sofa is a surface: the cloth, the foam, the gilding. Everything that has to last is structure: the frame, its joints, the carving. So the two are deliberately separated here. The upholstery is fixed so it can be stripped and rebuilt without cutting into the frame. The gold is laid on a finished carved surface that can be cleaned back and re-leafed. The joints are mortise and tenon, glued and pinned - which can be knocked apart and re-glued by a restorer decades from now, where a screwed or stapled frame simply cannot.
That is why the carving is worked before finishing and why the show wood is finished before the upholsterer touches it. It means that in twenty years, when the velvet has had its life, you reupholster a sound teak frame in a new cloth rather than throwing the whole sofa away.
Velvet, for its part, is upholstered with the pile running in one consistent direction across every panel - get that wrong and the colour appears to change from panel to panel.
