The mechanism inside the Sihoo Doro S300 features a pair of elastic plates made of aerospace-grade glass fiber, the same material used in spacecraft. This choice ensures high elasticity and adjustability, mirroring the robustness required in space exploration. The result is a revolutionary weightless recline experience.
A weightless recline experience
With the help of elastic plates made of aerospace-grade glass fiber inside the mechanism, regardless of your size and weight, you can adjust the tension to suit you. Whenever you need to relax a bit during your work, you can smoothly recline on the Sihoo Doro S300, stop at any angle you want (without the need to lock the backrest at a certain angle), and return to an upright position effortlessly.
Lumbar support that cradles your back
The wing-like dual dynamic lumbar support consists of two separate pads, offering comprehensive and dynamic support for your lower back, regardlessly of your body shape and sitting posture. Additionally, the gas lift allows you to fine-tune the lumbar support (90°-105°) for a perfect fit.
Comfort for the entire back whatever your size
The upper half of the backrest can be adjusted separately in 5 levels, providing adequate support to your shoulders and neck, whether you're 5' (150 cm) or 6'3" (190 cm). Meanwhile, the lumbar support stays in the right place to perfectly support your lower back.
Coordinated support for the full body
The dual dynamic lumbar support, shaped like wings, features two pads for flexible lower back support, suiting different body types and sitting positions. The gas lift allows precise adjustment of the lumbar support from 90° to 105° for an ideal fit.
Rest your head in spacious softness
With the soft-to-the-touch headrest that perfectly contours to the curve of your neck while providing a generously sized surface, you can comfortably rest your head on the side and relax from your tasks.
Award-winning esthetics
Sihoo Doro S300, a winner of a German Design Award, is not only comfortable to sit in but also pleasing to look at. The main structure of the chair is crafted from a single piece of aluminum alloy, created through 13 procedures to achieve its beautiful and magnificent appearance.
Cloud-like comfort
The mesh materials of Sihoo Doro S300 are woven in a special way with Italian velvet and DuPont TPEE. The result is that the mesh is highly elastic, durable, pressure-relieving, and soft to the touch.
Shock-absorbing, pressure relieving
To provide a more pressure-free seating experience, the Sihoo Doro S300 comes equipped with a suspension system. This system effectively absorbs shock when you sit down on the chair and dynamically adjusts to changes in your seating position.
Robustly built, rigorously tested
Engineered with premium materials and in leading crasftmenships, Sihoo Doro S300 also underwent numerous tests before being delivered to your hands. It's also BIFMA and SGS certified for extra peace of mind. Enjoy years of comfort with your Doro S300.
6D armrests for arm support
in all positions
The armrests of the Sihoo Doro S300 lead the industry by providing adjustments in six directions, ensuring optimal support for your arms, regardless of your sitting position.
Easily adjustable, perfectly suitable
All controls are positioned on your right-hand side, allowing you to effortlessly adjust the height, seat depth, recline, and recline tension. The extensive adjustability also ensures that Sihoo Doro S300 comfortably accommodates various body shapes.
"Moreover, the entire seat will coordinate when you recline with it, something that very few chairs of this style do..."
"'Defying gravity, Redefining Comfort' is no exaggeration. This ergonomic office chair is packed with innovative features that promise a weightless and comfortable experience."
"...which not only utilizes the latest sixth generation of the mechanism and is addressable in almost all joints and springs but also offers the best weightless reclin experience I've had so far..."
"All of this amounts to a really crazy experience when it comes to the arm adjustability. Most chairs have a completely flat arm but with this the sweep seems to give a little bit more support to my whole arm rather than just my elbow which is rather nice."
