The Egg Chair is a design by Danish architect and designer Arne Jacobsen. It is an iconic and widely recognized piece of furniture that is known for its distinctive egg-shaped form and comfortable, ergonomic design.

Jacobsen designed the Egg Chair in 1958 as part of a commission for the Royal Hotel in Copenhagen, Denmark. The chair was designed to be used in the hotel's lobby and bar area, and Jacobsen intended it to be a comfortable and welcoming place for guests to sit and relax. The chair's unique form and innovative use of materials made it an instant success, and it has since become a classic of modern design.

The Egg Chair is made from a molded foam shell that is upholstered in fabric or leather, and it sits on a swivel base that allows it to be rotated in any direction. Its ergonomic design conforms to the body's natural shape, making it a comfortable and supportive place to sit. The chair's egg-shaped form and sleek, modernist style have made it a popular choice for both residential and commercial settings, and it is often used in homes, offices, and public spaces around the world. The Egg Chair is considered a significant and influential piece of modern design and continues to be admired and collected by design enthusiasts and collectors.
