The term 'chair-seat maker' refers to a caner, someone who weaves cane into furniture seats. Caning is a traditional craft that has been used for centuries to make chairs, sofas, and other furniture items. Caners use natural materials such as rattan, reed, and willow to create intricate patterns and designs in the seats of furniture. The craft requires a great deal of skill and patience, as it involves weaving the cane into the seat frame and then securing it with glue or nails. Caners are highly sought after for their expertise in this craft, and their work can be found in many homes and businesses.
