Description

The SIHOO Doro C300 Ergonomic Office Chair is engineered for posture-focused comfort during long work sessions. Its dynamic lumbar support adapts as you move to help maintain healthier seated alignment, while a breathable all-mesh seat and back promote airflow to keep you cooler across extended use. Designed for modern workspaces, the C300 delivers ergonomic support, responsive comfort, and a clean, professional aesthetic for home offices and everyday work.

The Doro C300 is built to reduce sitting fatigue by combining self-adaptive lower-back support with a structured yet flexible mesh seating system. A supportive headrest and multi-direction armrests help you fine-tune your upper-body posture for focused work, calls, and long sessions at the desk.

Whether you remain upright for productivity or ease into a relaxed recline, the C300 maintains balanced support while allowing natural movement. A waterfall-style seat edge helps reduce pressure behind the knees for improved comfort during all-day sitting.
