This chair is made entirely of molded plywood. All of the joints are connected in smooth curved lines without any gaps. Although the prototype was made of solid wood for production efficiency, the original design was composed of a curved plywood seat, a backrest made of compound-curved plywood of varied thickness, and legs that have wood between the plywood at the corner sections. The combination of molded plywood and finger joints provide elegant style, yet with ample strength and lightness, and are achieved using the minimum amount of materials.

The title was inspired by the name given to the trajectory of a space probe that is caused by gravity-assist, known as “swing-by”. (It is called “Fly-By” in Japanese).
