What is the meaning of the furniture term H-Stretcher?

H-Stretcher is a term used in furniture design and construction to refer to a structural component often found in chairs, stools, and benches. It is a horizontal support that connects the legs or posts on either side of the furniture, forming the shape of an H. The purpose of the H-Stretcher is to add stability, strength, and reinforcement to the piece of furniture, preventing wobbling or collapsing. It helps distribute weight evenly and provides additional support for the legs, making the furniture more durable and long-lasting. Typical stretcher construction, as in some Windsor chairs. From front to back leg on each side is connected through the middle by a third.
