upholder

n. supporter, one who maintains and defends

Upholstery is the work of providing furniture, especially seats, with padding, springs, webbing, and fabric or leather covers. The word "upholstery" comes from the Middle English words up and holden, meaning to hold up. The term is applied to domestic furniture and also to applications in automobiles and boats. A person who works with upholstery is called an upholsterer; an apprentice upholsterer is sometimes called an outsider or trimmer.
