Sihoo Doro S300

Ergonomic Office Chair: The Ultimate Choice for Tall and Heavy Users

doro s300 Coordinated support for the full body

Superior Ergonomic Design for Tall Individuals

The Sihoo Doro S300 office chair is engineered to cater to taller person, with a focus on adaptability and full-body support. Its standout feature is the Anti-Gravity Mechanism, which allows the seat and backrest to move in unison as you recline, maintaining optimal spinal alignment at any angle. This design prevents the "slumping" effect common in standard chairs, ensuring your legs and torso remain properly supported even at greater heights 1.

For tall users (up to 6'5" or 195 cm), the chair’s 4-position adjustable backrest can be raised or lowered by 6 cm (2.36 inches), accommodating longer torsos. The 6D armrests further enhance comfort, allowing adjustments in height, width, and angle to suit longer arm spans 16.

Enhanced Support for Heavyweight Users

Built to withstand rigorous daily use, the Sihoo Doro S300 boasts a sturdy aluminum frame and BIFMA/SGS certifications, ensuring durability and safety for users up to 300 lbs. The chair’s adaptive lumbar support dynamically adjusts to body movements, distributing weight evenly and reducing pressure on the lower back—a critical feature for heavier individuals 16.

The breathable Italian velvet mesh promotes airflow during extended sitting sessions, while the anti-slip seat cushion provides a stable base without compromising comfort.

Customizable Comfort for Long Hours

Tall users often struggle with shallow seat pans, but the S300 addresses this with its ergonomic seat design. While the seat depth isn’t explicitly adjustable, the contoured shape and flexible mesh material prevent edge pressure on the thighs. Combined with the 90°–105° tilt range, the chair allows taller users to recline comfortably without sacrificing posture.

Awards and Real-World Performance

Winner of the 2023 German Design Award, the S300 merges aesthetics with functionality. Users praise its ability to alleviate back pain and adapt to diverse body types. While some taller individuals note minor limitations in seat depth (as seen in Sihoo’s C300 model), the S300’s synchronized seat-backrest movement mitigates this issue, offering a "floating" sensation that reduces fatigue.
