Check Out How Doro S300 Was Designed

Feel weightless in Doro S300

Utilizing elastic plates made of aerospace-grade glass fiber, the Sihoo Doro S300 offers personalized tension adjustment, catering to individuals of varying sizes and weights. During work, you can effortlessly recline on the Sihoo Doro S300, pausing at any angle without needing to lock the backrest, and returning to an upright position is also smooth and effortless.

Comprehensive lower back support

The dual dynamic lumbar support, resembling wings, comprises two distinct pads to provide comprehensive and adaptable lower back support, accommodating various body shapes and sitting positions. Moreover, the gas lift feature enables precise adjustment of the lumbar support within the range of 90° to 105°, ensuring an optimal fit.

Comfort for the entire back

The upper section of the backrest can be adjusted independently in five positions, ensuring adequate support for your shoulders and neck, whether you are 5 feet (150 cm) tall or 6 feet 3 inches (190 cm) tall. Simultaneously, the lumbar support remains optimally positioned to effectively 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.

Soft spacious headrest

Crafted with soft-to-the-touch material, our headrest gently contours to the curve of your neck, ensuring a perfect fit every time. The generously sized surface area allows you to rest your head comfortably on the side, whether you're unwinding after a long day or taking a brief respite from your tasks.

Award-winning design

Sihoo Doro S300, a recipient of the esteemed German Design Award, boasts both comfort and visual allure. Crafted from a single piece of aluminum alloy, its main structure undergoes 13 meticulous procedures to achieve its stunning and elegant esthetics.

Cloud-like softness

Sihoo Doro S300 employs a distinctive weaving technique that blends Italian velvet with DuPont TPEE for its mesh materials. Consequently, the mesh delivers outstanding elasticity, durability, pressure relief, and a luxurious soft texture.

Pressure-relieving seating

Sihoo Doro S300's suspension system consists of four springs that effectively absorb shock when you sit down on the seat cushion. Moreover, the suspension system dynamically adjusts to changes in your seating position, ensuring consistent comfort no matter how you sit.

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

Sihoo Doro S300 sets the industry standard with its armrests, which offer adjustments in six different directions. This feature ensures that your arms receive optimal support, regardless of your sitting position.

Complete control within your reach

The controls are conveniently situated on the right-hand side for easy access, enabling you to smoothly regulate the height, seat depth, reclining angle, and tension. This extensive range of adjustments ensures a comfortable fit for individuals of various body types when using the Sihoo Doro S300.

"Moreover, the entire seat will coordinate when you recline with it, something that very few chairs of this style do..."

Léo - TechMaker

"'Defying gravity, Redefining Comfort' is no exaggeration. This ergonomic office chair is packed with innovative features that promise a weightless and comfortable experience."

Robin's Fun Playtime

"...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."
