Yoyo Sit-Stand Chair

The Yoyo Sit-Stand Chair is a sleek, ergonomic task chair built for the way modern offices actually work - moving between focused desk time and higher perched postures throughout the day. With a generous height range, this swivel chair adapts to standing desks and traditional workstations alike, keeping you supported wherever you choose to sit.

Comfort comes from a backrest and seat made with moulded foam, finished in premium Gabriel Mozart FC3103 charcoal fabric - a textile woven from 100% renewable polyester. The 323W wire-control mechanism and 15mm ratchet backrest adjustment let you fine-tune the fit, while the Class 4 XieQiang gas lift delivers smooth, reliable height changes. A black nylon five-star base with top grip treads and 60/25 PU castors keeps the chair stable and mobile across your workspace, supporting users up to 110kg.

Ideal for agile offices, hot-desking environments and any setting where sit-stand flexibility matters, the Yoyo balances clean design with genuine durability. It is GreenGuard Gold certified for low chemical emissions and backed by a 10-year warranty for lasting peace of mind. Like everything from EFI Furniture, the Yoyo Sit-Stand Chair is chosen to bring quality, comfort and value to Australian commercial workspaces.
