Independent backrest
Floating tilting experience
Thanks to the anti-gravity mechanism, you can enjoy perfect relaxation at any time while working, with a seamless change between tilting and straightening, all without locking the backrest.
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.
Comfort for the entire back
The upper backrest can be individually adjusted to five positions to ensure perfect support for shoulders and neck – whether you are 150 cm or 190 cm tall.
Comprehensive lumbar support
The dual dynamic lumbar support, reminiscent of wings, consists of two different cushions that offer tailored support, while the gas lift allows for precise adjustment – for optimal comfort.
