Unprecedented comfort and concentration encompassed in a "low-seat, rear-tilt" design. Cruise was born of an industry-academia joint project. The theory behind the "low-seat, rear-tilt" concept was conceived in a joint development project with human body engineering advocate and Keio University Department of Science and Technology Professor Nobutoshi Yamasaki. Human body engineering seeks to understand the physical characteristics of the human body in order to elucidate essential needs of the body and apply that knowledge to ergonomic product design and engineering. The low-seat, rear-tilt work posture places minimal stress on the body was developed through numerous experiments with form-variable chairs, desks, and other equipment.
