SIHOO Doro-C300 Ergonomic Office Chair (Hardware)
Official GBAtemp Review
Product Information:
It should be no secret that we here at GBAtemp love a good chair. And after all, why shouldn’t we? With so many of our chosen professions and hobbies requiring long hours at a desk, who wouldn’t want to make sure that the chair they’re spending all of that time in, is a quality one? There’s more than enough options to go around when it comes to a chair for your home office, though I see a lot of (oftentimes justifiable) criticism levied towards the racing-style gaming chairs; from a lower build quality, to a lack of comfort or proper posture support… none of which are issues that plague the subject of today’s Chairtemp discussion, the SIHOO Doro-C300. An ergonomically designed office chair, aiming to be as functional as it is comfortable and aesthetically pleasing. How does it fare on that front? Well that’s what we’re here to learn, isn’t it?

Some Assembly Required
Starting off the way all office/gaming chairs do, what you essentially receive is a big box of parts that need to be put together - much like a set of Lego that actually allows you to be productive both before and after the build process. Included with the chair parts, as expected, is all of the hardware needed to assemble it; namely, two durable hex keys that can be used interchangeably throughout the build, though my favorite was the one with the proper handle built into it. It was much more comfortable than the standard allen wrench style key, and actually felt like it was simpler to use as a result. The assembly instructions broke it down into a simple, 8-step process that took barely an hour to finish. Within no time, I had this brand new chair assembled, and I was finally ready to sit comfortably.
But can I sit in it?
Upon taking it for a “test drive” so to speak, the quality of the C300 was immediately apparent. The primary feature of this chair would have to be, in my mind, the mesh seat, back, and support pillows that comprise almost the entirety of the body. With this high quality, breathable fabric being the primary component for the chair, I was able to sit back, with excellent posture thanks to the ergonomic body design, and work on photo and video editing, as well as a bit of gaming on the side, for hours without getting uncomfortable. The head and backrests, a fully built-in feature of the body on this chair, rather than the added pillows you’ll find on most gaming chairs, helped promote proper posture in addition to the comfort. It’s an overall great sitting experience, which I hope one would expect from a chair that retails for $400, though here I do arrive at my first complaint; the seat size, itself, is a bit on the smaller size. The chair officially can support a weight capacity of up to 300 lbs, but I found myself feeling a bit cramped by the smaller real estate of the seat itself. This isn’t helped by the positioning of the armrests, the arms of which are pretty firmly sculpted in place, with the armrests themselves only able to pivot out about 75 degrees. This is all to say, it is a genuinely well built, breathable, and comfortable chair… but those on the bigger side will definitely find themselves feeling cramped eventually.
This leads well into the adjustable features of the chair, of which there are many; though not all as high quality as the others. For starters, the back, head, and armrests of the chair can all be adjusted by simply pushing or pulling on them; the headrest simply needing to be pressed down, while the back and armrests just need to be pulled up. It’s a convenient feature that lets you effortlessly adjust the chair to your specific liking, but it’s not without its flaws. See, the way to reset everything to basic position is to just pull up, or push down, past their maximum limit, at which point all adjustable pieces will return to their default positioning. This would be fine if there was any sort of indication during the adjustment process that you were at the limit, but there’s not. You simply push or pull too far, and have to start all over again. This is especially an issue with the armrest heights, which are, in my mind, impossible to tell when adjusting just what point they’re at. Still, though, this is more of a quirky flaw than a dealbreaker on the chair, and is easy enough to work with. An annoyance, more than anything. Raising the total chair height and reclining the back is done with the standard lever and chassis, and works as intended without any of these quirks. Ultimately this adds, in my mind, to the overall comfort potential of the chair, and is far from a reason to avoid it… but it is a quirky annoyance worth mentioning.
So at the end of the day, what’s the verdict on the C300 office chair? Well despite how much I decided to play up the temp’s love of these accessories, it’s still enough to make me a satisfied reviewer. Despite some quirks with the adjustments and a bit of a small seat that limits the appeal to bigger folks, this is still a really well built, comfortable office chair. The ergonomic design is a noticeable improvement in comfort and posture compared to sitting in one of my gaming chairs, and the breathable mesh fabric will definitely help during longer sessions of both work and play, especially once warm weather finally reaches my part of the world. At $400 retail, it’s even a pretty reasonably priced chair when you consider the design, build quality, comfort you get at this level. And when comparing prices with other major chair manufacturers, it’s clearly either on par, or even cheaper in some cases. With all of this in mind, the SIHOO Doro-C300 easily passes the test, in my mind, and is a chair worth sitting in.
Verdict
- Sleek, ergonomic design
- Comfort without killing your posture
- Affordable compared to other premium office chairs
- Adjustment method not optimized or ideal
- Not very friendly to larger folks
