Chair

Chair (/tʃɛər/; from Old French chaere "seat, throne," from Latin cathedra "seat") is a piece of furniture with a raised surface supported by legs, commonly used to seat a single person. Chairs are supported most often by four legs and have a back; however, a chair can have three legs or could have a different shape.

History

Chairs are of extreme antiquity and simplicity, although for many centuries and indeed for thousands of years there was little change in their design. The 20th century saw an increasing use of technology in chair construction with such things as all-metal folding chairs, metal-legged chairs, the Slumber Chair, the recliner and the butterfly chair.

Types of Chairs

There are many types of chairs that each have their own specific uses. Some of these include the armchair, dining chair, desk chair, rocking chair, and folding chair. Each of these chairs serves a specific purpose and adds to the functionality and aesthetics of a space.

Materials

Chairs can be made from a variety of materials, the most common being wood. Other materials include metal, plastic, and sometimes even materials like rattan or wicker. The choice of material often depends on the chair's intended use, the desired aesthetics, and the durability required.

Ergonomics

Ergonomics is the study of people's efficiency in their working environment. Ergonomic chairs, like the office chair, are designed to provide comfort and to avoid stress or injury. They often feature adjustable seats, armrests, backrests, and are usually on a swivel base.
