The materials and fabric used to cover and cushion furniture, especially seats, or the craft of making such coverings.

Upholstery → The word is derived from the Old French 'upholster' (meaning to furnish or provide with coverings) and the suffix '-ery' (meaning a place associated with a specific activity). Thus, upholstery refers to the craft or trade of providing furniture with coverings and padding.
Imagine a place where furniture is 'furnished' ('upholster') with beautiful coverings — that's what upholstery means.
