upholstery
upholstery
Noun
This term refers to the tactile and visual layer of furniture, evoking a sense of comfort, luxury, or wear. It encompasses both the visible outer fabric and the hidden internal padding, such as foam or springs, that provide structural support and softness.
As a mass noun, it describes the material in general or the professional trade of the upholsterer. Because it is uncountable, it does not have a plural form; one would refer to a piece of upholstery or specific upholstered items rather than using a pluralized version of the word.
