Renowned tech writer Tommaso Matteini recently sat down with the Sihoo Doro C300 ergonomic office chair and shared his thorough impressions in his detailed review on Ceotech. Designed to deliver unmatched comfort during extended work or study sessions, the Sihoo Doro C300 aims to combine functionality with advanced ergonomic support—and according to Matteini, it largely succeeds.
Comfort and Design Built for Endurance
The Sihoo Doro C300 is crafted with comfort and adaptability in mind, especially for those long hours at a desk. Matteini highlights its meticulous selection of materials and precision engineering that culminate in a chair capable of adjusting perfectly to different body shapes and postures. The chair’s dynamic lumbar support system stands out as a key feature—it automatically conforms to the natural curves of the spine without requiring manual tweaking. This adaptive mechanism, combined with the chair’s Body Movement tracking system, ensures continuous and personalized lower back support throughout the day.
Matteini also praises the chair’s flexible triangular backrest structure. The upper part of the backrest gently molds to the user’s back, offering consistent support even as the user shifts positions. Additionally, the adjustable headrest can be moved up or down, tilted forward or backward, and even rotated—allowing for customized neck support that prevents strain during prolonged sitting.
The breathable mesh fabric not only gives the Sihoo Doro C300 a sleek and modern aesthetic but also promotes excellent air circulation. Matteini notes that this design prevents the discomfort often caused by sweating after long contact with solid surfaces, a welcome relief during warm days.
Easy Assembly With Helpful Guidance
Matteini mentions that assembling the chair took him about 30 minutes—a reasonable time given the chair’s complexity. For first-time ergonomic chair assemblers, the process might take closer to 45 minutes due to the number of components involved. Thankfully, Sihoo supports users with a clear instructional video on YouTube, which Matteini considers very useful.
The assembly starts with attaching the chair legs to the central cylinder using the provided screws. The wheels snap into place firmly, requiring some force. The armrests can be installed later if preferred, making the setup flexible for users who want to take their time.

Extensive Adjustability for a Personalized Fit
Once assembled, the Sihoo Doro C300 offers a wealth of adjustments to tailor the chair to each individual. Matteini outlines the key adjustable elements:
- Seat height
- Backrest height, which also affects the position of the lumbar support
- Armrest height, rotation, and horizontal positioning
- Headrest tilt and rotation
The chair’s mesh fabric is soft and gentle on the skin, with an open weave that improves ventilation and comfort compared to conventional office chairs with closed upholstery.
A unique lever beneath the seat controls the chair’s pneumatic height adjustment and unlocks the recline mechanism. When the lever is pulled out, the backrest and armrests recline in unison, providing excellent comfort during relaxation breaks. Recline angles can be locked into one of three preset positions for stability.
The lumbar cushion is self-adjusting, eliminating the need for manual intervention. The backrest can be raised or lowered easily by pulling it up to lock into one of four positions or releasing it back to the base position.
Armrests feature seven height settings plus a reset position. They can also rotate up to about 75 degrees in six increments and slide forward or backward, allowing users to minimize friction and find the perfect arm support.
Final Thoughts: Solid, Comfortable, and Highly Adaptable
Matteini concludes that the Sihoo Doro C300 is a well-built, durable chair with no creaking or weak points. Its vast range of adjustments accommodates users roughly between 150 cm and 180 cm tall—and in Matteini’s opinion, likely even taller.
The breathable mesh fabric proved comfortable and ventilated during his testing, with no signs of discomfort or sweating after three hours of continuous sitting at a room temperature of 24°C. Matteini also reminds readers that it’s always recommended to stand or move every 30 minutes during sedentary work.
Above all, the chair allows for comfortable positioning not only for focused work but also for moments of relaxation, making it a versatile ergonomic choice for both office professionals and students.
If you’re looking for a modern ergonomic chair that offers extensive adjustability, smart lumbar support, and breathable materials, Tommaso Matteini’s review suggests that the Sihoo Doro C300 is a strong contender that ticks all the boxes.
