Look at the seat cushion on this chair and then at the seat rail below it. The damask pattern lines up across the gap. That is not luck, and it is not how most upholstered chairs are cut.
A damask this size has a long vertical repeat, and a chair has three separate surfaces stacked one above the other - the front rail, the loose cushion, and the inside back. Cut each of them from the roll as it comes and you get three unrelated fragments of pattern sitting on top of each other, which is why so many patterned chairs look busy without anyone being able to say why.
Our cutter works the other way round. The centre of one motif is found first and placed on the vertical centre line of the inside back. From there the cushion top is cut so its motif sits directly below, and the front rail below that. The roll is then cut around those fixed points, which wastes fabric - sometimes a great deal of it on a large repeat - and there is no way around that.
The result is a chair where the eye travels straight up the middle without snagging. Most people will never work out why it looks calm. They only see that it does.
