In a recent GizChina.it review, respected Italian tech writer Roberto Branni gave high praise to the Sihoo Doro S300 ergonomic office chair, calling it a revolutionary product for people who spend long hours at their desks. Built with an aerospace-inspired design and a clear focus on comfort, support, and premium materials, the Sihoo Doro S300 has made a strong impression — even on the first use.
“If sitting for long hours in the office has caused the classic lower back pain, the Sihoo S300 might truly help you find the right posture and bring some relief,” Branni writes.
Built Like a Luxury Car, Feels Like a Cloud
From the start, Branni emphasizes the solid build quality of the Sihoo Doro S300. Its full aluminum alloy frame exudes durability and elegance, while polished metal parts add a high-end, shimmering look that stands out in modern workspaces.
The chair’s signature cloud mesh upholstery — a blend of Italian fabric and DuPont TPEE — delivers unmatched breathability and comfort. Meanwhile, eco-leather armrests add a soft yet luxurious touch, rounding out the aesthetic and tactile appeal.
Anti-Gravity Recline: Smooth, Seamless Comfort
What truly sets the S300 apart, according to Branni, is its anti-gravity reclining system. This feature allows the chair to tilt gently and fluidly, avoiding the harsh jerks that can strain the back. The reclining function is synchronized with the armrests, creating a fully coordinated recline that supports the entire upper body for a more natural, restful posture.
“The backrest reclines with smoothness and without shocks, with armrests adjusting in tandem to provide even more comfort,” Branni notes.

$679.99Dual Dynamic Lumbar Support: A Back Saver
The Sihoo Doro S300 doesn’t stop at aesthetics or motion — it’s packed with thoughtful ergonomic features, most notably its dual-panel lumbar support system. This support adjusts hydraulically to fit your back, rather than forcing your body to adapt to the chair.
“Thanks to the two adjustable ‘wings’ for lumbar support, it’s the chair that adapts to your spine, not the other way around,” Branni explains.
In addition to the lumbar system, users can adjust the height of the backrest (up to 53 cm) and seat depth (up to 46 cm) using intuitive levers clearly marked with icons. The chair offers three recline angles: 100°, 110°, and 130°, catering to different working and resting postures.
6D Armrests & Advanced Suspension for Personalized Support
Roberto Branni highlights the Doro S300’s 6D armrests as a standout feature. These can be adjusted vertically, horizontally, and in height, allowing users to eliminate gaps between the desk and their arms — a detail that greatly improves typing comfort and posture.
Adding to the comfort is a quadruple suspension system built into both the seat and the backrest. These suspensions distribute pressure evenly, reducing discomfort during long hours of sitting.
Despite its 28 kg weight, Branni found the chair easy to move thanks to its smooth-rolling metal and plastic wheels, although he did note the lack of a brake system as a minor drawback.
Real-World Testing: 8 Hours a Day, 7 Days Straight
To put the Sihoo Doro S300 to the test, Branni used the chair for eight hours a day over a full workweek. His verdict?
“We can confidently say that not a single backache or lumbar pain showed up. The comfort is truly incredible.”
Though he admitted that the initial sitting experience felt unusual, within 10 minutes, his back adjusted, and sitting at his desk began to feel “as comfortable as lying in bed.”
Design Meets Performance
The Sihoo Doro S300’s sleek, futuristic look was another plus for Branni, who said it fits beautifully in a modern workspace. While the price may seem high, he believes it’s fully justified given the advanced technology, materials, and ergonomic design.
Final Thoughts: A Serious Chair for Serious Work
Roberto Branni’s review is ultimately a glowing endorsement of the Sihoo Doro S300, calling it a must-have for anyone suffering from back pain or spending long hours working at a desk. With its anti-gravity mechanism, adjustable lumbar wings, and cutting-edge build, it’s more than just a chair — it’s a wellness investment.
