The Story Behind This Sofa
Upholstery on a carved show-wood frame is an entirely different craft from upholstery on a plain box, and it happens last for a reason: the cloth has to be worked up to a carved edge that is already finished and gilded, with no margin for error. A slipped tack or a stretched seam cannot be corrected by trimming the wood back.
So the upholsterer works to the frame rather than the other way round. The pattern is cut and centred before anything is fixed - on a damask this large, the motif has to sit true on the centre line of the back panel and repeat symmetrically across all three seat cushions, which means more cloth is bought than the finished area requires. A pattern that drifts off centre is the single most common giveaway of cheap upholstery on an expensive frame.
The back panel is built up in layers over webbing, the arms are rolled and stuffed to hold their shape under a hand rather than collapsing, and the fabric is finally brought up tight to the gilded carved edge and secured where the trim will conceal the line.
