Our Verdict

  • Made from breathable mesh
  • Adaptable
Reasons to avoid
  • Expensive
  • Adjustable armrests are fiddly
  • Brief assembly instructions

The Sihoo Doro C300 is one of Sihoo’s mid-tier chairs. The manufacturer specializes in ergonomic chairs with a breezy mesh backrest made to keep people cool and comfortable while they game (or work). It’s more expensive than something like the Sihoo M57, but you’re paying for more adjustment options and a higher build-quality that can match the unique shape of your body. Though it sits below the advanced S300 (with its aerospace‑grade fiberglass and weightless recline feature), that’s an expensive chair that has more features than most people will need in a chair.

You’ll see it pop up in our list of the best gaming chairs and the best office chairs because it’s a versatile piece of furniture that, despite initially appearing daunting, is very easy to build and adjust to your needs. It always makes you feel supported as if it’s moving in real-time in response to your body and movements, and it looks great too. It may lack the seat depth adjustments of the Sihoo C300 Pro, or the award-winning build quality and weightless recline features of the Sihoo S300, but it does offer a more affordable price point than them, as it costs several hundred dollars less.

This product’s quality is evident even during the assembly process. The chair arrives flat-packed and is exceptionally well-packaged. Molded cardboard safeguards the backrest, while bubble wrap and small cardboard boxes protect the smaller components. They even use red bubble wrap to distinguish the left arm from the right. If you remove it, don’t worry—each side is conveniently labeled with an “L” or “R.”

You get a pair of gloves for assembly, a thoughtful touch, though they might be a bit snug for larger hands. The best part is the packet of screws and components. Each packet clearly labels the parts and separates the screws into sections for each step, eliminating the need to search through a bag for the right one. There are even plenty of spare screws included. However, don’t forget the washers! I did, and had to remove some screws to add them, which resulted in a minor scratch on the chair—fortunately, it’s at the bottom and out of sight.

A minor downside to the assembly process is the brevity of the instructions. When I saw the small instruction page, I decided to wait for my partner to get home. In reality, assembly is very simple, but as someone who thrives with detailed picture instructions, it felt a bit overwhelming. However, I soon realized that I had nothing to worry about and that it was not a two-person job. It would have been nice to have more thorough instructions.

Aesthetically the Sihoo C300 is very pleasing to the eye. It comes in both black and white and easily fits in with most decor. It has a waterfall-shaped seat for weightless seating meanwhile offering a unique style. This chair is brimming with attention to detail, evident in features like the decorative cover for the gas lift. While it still looks great even without it, these thoughtful details truly elevate its design.

It’s made from fully breathable mesh. Whether it’s a hot summer day or winter with the radiators on, this design ensures your back stays cool and comfortable, preventing any sweaty or sticky discomfort while you work. No one likes that peel away from a seat after sitting for a few hours.

Dimensions-wise, it is advised that the chair offers optimum comfort for people between 150- 180cm tall. The seat is big enough for an average person with a width of 49.5cm. As a larger woman, I found the chair comfortable and had no space issues. The chair is not too bulky either. Compared with something like the GT Omega Pro XL gaming chair (which measures 45cm- 70cm in width), it’s much more compact. However, if you want extra space then the Sihoo C300 Pro might be literally and figuratively a better fit.

The Sihoo C300 is all about comfort. The backrest has a flexible triangular frame that moves with your upper body. This high-back chair features a four-position adjustment, allowing for 6cm (2.36 inches) of vertical movement to accommodate different heights. Adjusting it to the highest position will automatically return it to the lowest level, ensuring a perfect fit every time. The self-adaptive lumbar support also moves with your body, providing continuous support and comfort to your lower back. It also has an adjustable headrest for neck support.

It has 3D armrests that adjust in three directions and synchronize with your recline, allowing you to relax your arms in any position. However, I found the armrests difficult to adjust. When moving them up, they seemed to slip back down again. My other half figured out how to make them stay up, but after a while of pushing and pulling, I still couldn’t figure it out.

The chair features an intelligent weight-sensing mechanism that supports up to 136kg, adapting to the user’s weight for an effortlessly balanced reclining experience. As a larger lady, I always worry that chairs with a reclining feature will be top-heavy, but I needn’t worry with this one. I could tilt to the lowest recline and maintain a comfortable posture.


The Sihoo C300 delivers on its promises. It’s incredibly comfortable, and as someone who tends to move a lot while working, this chair accommodates my shifting and shimmying effortlessly. It feels like the chair moves in sync with me. I’ve been able to sit for hours without experiencing any discomfort in my back or neck, which is a huge relief as someone prone to tension headaches. The headrest provides excellent support, adding that extra level of comfort.

The recline feature is impressively deep and feels secure. Additionally, the chair boasts excellent casters with smooth bearings, making it glide effortlessly over the carpet and allowing for easy movement. It’s a significant upgrade from the stiff-wheeled chairs I’ve used in the past. Overall, this chair is quite possibly one of the best I have sat in!

The Sihoo C300 chair stands out as a remarkable choice for those seeking comfort, functionality, and style. With its robust build and thoughtful design, it caters to a diverse range of user needs. While the assembly process may initially seem daunting for those who prefer detailed guidance, the chair’s simplicity soon becomes evident, requiring minimal effort for setup.

Its fully breathable mesh ensures comfort year-round. Comfort is paramount with the Sihoo C300, boasting features like self-adaptive lumbar support, adjustable headrest, and 3D armrests. While some users may encounter challenges adjusting the armrests, the chair’s overall performance more than compensates for minor inconveniences. Marketed as an office chair, this chair is perfect for anything. Gaming, working… watching TV or painting Warhammer.
