English: Free picture of a wooden Chair.

A chair can have three legs or could have a different shape depending on the criteria of the chair specifications.

In ancient Egypt chairs appear to have been of great richness and splendor.

Chair design considers intended usage, ergonomics, as well as non-ergonomic functional requirements such as size, stackability, foldability, weight, durability, stain resistance and artistic design.

People have used wood for millennia for many purposes, primarily as a fuel or as a construction material for making houses, tools, weapons, furniture, packaging, artworks, and paper. Wood can be dated by carbon dating. Which is when two hard woods flirt with each-other.
