Here's a very interesting retro chair. It came into our shop in an old mint green fabric, with a torn bottom fabric, and missing centre button.
Several of the string ties were torn loose (not that clearly seen in this photo):
Back springs re-tied, frame repaired, and legs re-sprayed in fresh black paint.
Finished chair. Note that the fabric is a velvet/velour type with a pattern of leaves (see last photo).
