A zaisu is a Japanese chair with a typical chair back but no legs. They are frequently used for relaxing beneath hot kotatsu tables and are frequently found in traditional rooms with tatami mats. Seiza, which involves kneeling with the weight on top of the lower legs that are folded beneath the body, is considered the proper seating position in Japan. The zaisu, where the back is supported and the legs can be placed more easily, is preferred by many because this can become unpleasant after extended periods of time or for persons who are not used to it. People in our nation experience too many spinal issues due to the variety of chairs available. Their incorrect sitting posture and the lack of ergonomics in the design are the causes of these issues. The primary need is Japanese sitting chairs are not available in Indian markets. Contradictory about this chair is it is available in international market, but the price is comparatively high in Indian currency. Approximately the cost of Japanese chair in international markets is about 300$ which is around 32,000 rupees in Indian currency for importing. So, in our project we are studying about the mechanism and try to develop a Japanese sitting chair with comfort and affordable price with perfect ergonomic posture.
