Enjoy Sitting / Furniture

How long does a chair keep our pleasure? It is difficult for people to sit long with one posture. So, I suggested a chair that can enable people to feel pleasure in modern society that works to be done being seated are increasing. The main concept of the product above is freedom while being seated. Most of all, I studied behaviors we can show using chairs, and made one that can satisfy the typical needs of people.(needs to sit on the high/low places, needs to gather or spread legs, needs to lean comfortably)
