About Oyoga Sedes Modularis

Oyoga sedes modularis est ad usum communem in locis quietis communibus destinata. A sellis fixis diversa, Oyoga structura iuncturae versatilis utitur, ita ut dispositio ex sede trium personarum in sedem sex personarum secundum usentium numerum mutari possit. Quaeque sedes est pila yogae, quae mollitiem addit et exercitationem levem sedendo permittit. Pila etiam sursum verti potest ut dorsale sedis proximae serviat. Materiae elasticae commoditatem praebent, et connexus metallici partes stabiles et ad substituendum simplices custodiunt. Grana mali punici formam inspiraverunt, tamquam signum unitatis.

Unique Properties: Although traditional chairs are usually fixed, Oyoga uses a rotating joint structure, allowing it to change shape according to the number of people or the usage scenario, from a three-person seat to a six-person seat, providing users with more flexible usage. Oyoga incorporates design elements of yoga balls to enhance health functionality. Users can do some light exercises while sitting and can easily remove them when replacement is needed.
Dimensions & Packaging: Central column height: 0.6 m
Yoga ball diameter: 0.8 m
Rotating rod length: 1.1 m
Modular connector size: 0.2m × 0.1m
Tags: Flexible, Interactive, Comfortable, Sustainable, Versatile
Production Technology: Oyoga uses a combination of elastic materials and yoga balls to provide a more comfortable sitting experience, and the connector is made of metal, which is not easy to shift when replaced, and is more robust.
Design Challenge: The design of the Oyoga involves a rotating and deformable seat structure, so ensuring the safety of the mechanical structure is crucial.
Research: Focused on transforming a yoga ball from a solo activity to a group interaction while ensuring comfort and fun, a fun interactive multi-functional yoga chair aims to address this problem, collecting data through field research, surveys and random interviews, our team identified key elements such as wellness, interaction and fun through mood boards and mind maps. The study guided the design of the Oyoga multi-person yoga chair, highlighting the need for open, interactive Spaces, using a modular, deformable design with rotating and connected seats that can change layout for group use and interaction, and the final design using yoga ball materials and rotary connectors that allow the seat to deform during use. Increase the fun and interactivity during breaks.
Inspiration: We have designed a multi-functional yoga chair, aiming to promote interaction and entertainment. By utilizing the flexibility of elastic materials and the softness of yoga balls, it offers a comfortable and adaptable seating option, allowing users to experience the perfect blend of health and fun during activities. Inspired by pomegranate seeds, its design symbolizes unity and friendship, and this chair can accommodate multiple people.
Project Duration: At present, our project has successfully established a cooperative relationship with China Academy of Art, and contacted manufacturers to carry out large-scale production of products. Pass with various college cafes (Heh Heh star people, big black house...) After in-depth communication and coordination, the person in charge decided to make full use of the idle rest space outside the cafe and carefully arrange the seat products designed by us, aiming to provide a comfortable and convenient rest environment to attract more students of China Academy of Art who are eager to relax after intense learning to come to consume experience.
Operation Flow: We designed a deformable, multifunctional seat with a rotating spherical connector that changes the shape of the seat. Users can flexibly adjust the shape of the seat according to the number of people and scene needs, from three seats to six seats. The yoga ball is connected to the base by a rotating mechanical structure that allows the seat to be flipped up as a backrest for the seat next to it. OYoga simply uses mechanical splicing to put all the pieces together.
