A piece of furniture consisting of a seat, legs, back, and often arms, designed to accommodate one person.
Furniture design is defined as fashioning goods for seating or storage from raw materials. Within this broad definition, humans have been designing furniture since they first placed rocks near the fire pit for the express purpose of sitting.
Design by definition, though, implies the creation of an object that is not only functional but aesthetically pleasing. The concept of form follows function is a mantra among furniture designers, and for good reason. The rock can function as seating, but it is the form that ultimately turns function into comfort.
Few objects tell the history of modern design as eloquently as the chair. Aesthetics trends, the emergence of new technologies, ergonomics, social and cultural developments are all reflected in the evolution of chair design.
Chair design considers intended usage, ergonomics (how comfortable it is for the occupant), as well as non-ergonomic functional requirements such as size, stackability, foldability, weight, durability, stain resistance and artistic design. Intended usage determines the desired seating position.
