Lumbar support that wraps around your back

The wing-like, dual lumbar support consists of two independent cushions that provide dynamic support, regardless of body shape or sitting position. The gas lift allows for precise adjustment (90°–105°) for customized back support.

Coordinated support for the entire body

The seat cushion and armrests of the Sihoo Doro S300 automatically adjust to the position of the backrest when leaning back, ensuring seamless, relaxed sitting.

Cloud-like softness

The innovative weaving technique of the Sihoo Doro S300 combines Italian velvet with DuPont TPEE for the mesh, which combines exceptional elasticity, durability and luxurious softness.

Pressure-relieving seat

The Sihoo Doro S300's four-spring suspension system absorbs shocks and dynamically adapts to your seating position to provide consistent comfort at all times.

Robustly built, rigorously tested

Made with the highest quality materials and masterful craftsmanship, the Sihoo Doro S300 has not only passed rigorous testing, but is also BIFMA and SGS certified – for your absolute safety.

Soft, spacious headrest

Our headrest, made from particularly soft material, gently adapts to the curvature of the neck and offers both flexibility and comfort – perfect for relaxing or resting.

WE WERE RECOGNIZED BY

"I never thought I'd say this, but I've finally found a chair that's more comfortable than my Herman Miller office chair."

"It looks stylish, but of course that alone is not enough – the S300 is also really comfortable and impresses in everyday office life."

“…with an ‘anti-gravity mechanism’ that allows the chair to move smoothly into any desired position and stop there without needing to be locked.”

"Nevertheless, the full mesh surface and curved structural elements give it a high-tech aesthetic that blends seamlessly into any gaming setup."
