Fine Arts and Art Installation Design Oyoga Chair by Zhejun Zhang Oyoga is a modular seat designed for group use in shared rest areas. Unlike fixed chairs, Oyoga uses a rotating joint structure, so the layout can change from a three person seat to a six person seat according to the number of users. Each seat is a yoga ball, which adds softness and allows light exercise while sitting. A ball can also be flipped up to act as a backrest for the seat beside it. Elastic materials provide comfort, and metal connectors keep the parts stable and simple to replace. Pomegranate seeds inspired the form as a symbol of unity.
