Riki Windsor is a traditional English Windsor chair that has been redesigned to suit the Japanese physique and living environment from Riki Watanabe's particular perspective. The chair is the result of a sophisticated fusion of beauty and technology, such as the back spokes of varying thickness, the frame penetrating through the seat from the arm to the leg beam, etc.

Riki Watanabe was born in 1911, established his office in 1949, and worked as a director of Japan Industrial Design Association to support setting up design-related organizations such as Japan Design Committee, Craft Center Japan, etc.
