When it comes to ergonomic office chairs, it takes a lot to impress a seasoned reviewer. But for Jason Bouwmeester of Techaeris, the Sihoo Doro C300 did more than impress—it became his new favorite. In a detailed review published on Techaeris, Bouwmeester called the Doro C300 “the most comfortable ergonomic office chair [he’s] ever used.” Let’s dive into what made this chair stand out for him across design, ease of use, and most importantly—comfort.
A Refined, Functional Design
At first glance, the Sihoo Doro C300 looks like a typical high-end best office chair. Its sleek, premium aesthetic features mesh and plastic construction, giving it a modern, breathable design. But as Bouwmeester points out, the chair diverges from tradition in some important ways.
One of the key differentiators is the mesh seat, replacing the more common foam cushion. This design choice allows for better airflow and suspension, which contributes significantly to comfort during long sitting sessions. The armrests, which are attached to the back frame instead of the seat, are adjustable both vertically and horizontally, though Bouwmeester notes that while they’re functional, they aren’t the most cushioned or luxurious.
The back frame also deserves special mention. It includes a floating “Y” shaped piece with a hidden hinge that allows for forward and backward tilt. The integrated lumbar support, combined with the flexible mesh and structured frame, helps the chair contour naturally to the user's spine. On top, the adjustable mesh headrest offers multiple adjustment options, tilting up, down, and forward—both independently and via its supporting stem.

Assembly: Straightforward with Minor Hiccups
The Sihoo Doro C300 arrives in about 20 parts and takes roughly 45 minutes to assemble. Bouwmeester found the instructions mostly clear, although some diagrams required a bit of squinting. The overall process is standard for ergonomic chairs, involving the assembly of the base, gas lift, mechanism, seat, backrest, and armrests.
The one minor issue he encountered involved the armrest brackets, which required a bit of trial and error to position correctly. Despite this, the final construction felt sturdy and thoughtfully engineered.
Ease of Use: Intuitive Controls
Once assembled, the Sihoo Doro C300 is easy to use. The height adjustment lever is located on the right side and doubles as the recline control. Reclining is simple: pull the lever out, lean back, then push the lever in to lock the chair in one of three recline positions. Although Bouwmeester noted that the backrest may shift slightly after locking, it wasn’t a deal-breaker.
The armrests, while lacking locking levers, offer intuitive adjustment. You can raise or lower them with a simple upward pull, and reposition them by twisting inward or outward—six positions in total. Bouwmeester appreciated the flexibility, finding one or two clicks inward ideal depending on the day.
Unmatched Comfort for Long Workdays
Comfort is where the Sihoo Doro C300 truly shines—and where it won over Bouwmeester completely. He had previously used an ergonomic chair with a mesh back and foam seat, which he found generally comfortable. But the Doro C300's fully mesh seat and back were a revelation.
He described the experience vividly: “My body almost literally melted into the SIHOO Doro-C300 ergonomic office chair the first time I sat down in it.” Over two months of regular use—eight hours a day, five days a week—he reported no hip pain or discomfort, which he occasionally experienced with his previous chair. The mesh suspension offers just the right blend of support and softness, adapting to the user’s body without pressure points.
Final Thoughts: A New Benchmark in Ergonomic Seating
Bouwmeester’s conclusion is unambiguous: the Sihoo Doro C300 isn’t just a great ergonomic chair—it’s the best he’s ever used. From the intelligently engineered frame and all-mesh construction to the customizability of the recline and armrests, it delivers on every front that matters for long-term users.
While some minor gripes—like the stiffness of the armrests or slightly tricky assembly steps—are worth noting, they do little to detract from the chair’s overall excellence.
If you’re someone who spends long hours at a desk and values ergonomic support without compromising on comfort, the Sihoo Doro C300 is more than worth a look. According to Jason Bouwmeester, it just might redefine what you expect from an office chair.
