Sihoo Doro C300 Pro V2 review: A robust ergonomic office chair with more features than you probably know what to do with

The Sihoo Doro C300 Pro V2 aims to keep the premium chair styling of some of Sihoo’s other chairs while also being a bit more wallet-friendly. Not everyone has north of $1,000 to drop on an ergonomic chair, and for those who do, they likely don’t want to spend it on just any chair; they want to make sure it’s a good value.

That’s where the C300 Pro V2 comes in. This chair obviously reminds me a lot of the other Sihoo Doro chairs I have tested. But it also reminds me of the Hinomi line of chairs, with a thousand areas to adjust to make it comfortable.

Sihoo Doro C300 Pro V2: Unboxing and First Impressions

My unboxing experience for the Sihoo Doro C300 Pro V2 was unique in a few ways. First of all, I had to have two delivered. My first model had a damaged wheel, but when flagging to Sihoo, they sent me a second chair.

Once I got the second chair, I had just assembled one of the fastest and easiest chairs (of the ones I had to actually assemble, some come fully assembled), so my tolerance for building is slightly tweaked. That being said, assembly took a full 30 minutes, with about 8 minutes just for unboxing everything. Sihoo has always been a company with many pieces, and they ensure that every piece is properly packaged individually, resulting in a lot of material to remove from the individual elements before assembly.

While assembling, I noticed that the letters on the included diagram did not match anything on the pieces, but instead matched the diagram. I then had to refer to the diagram to confirm which screw type to use, for example. Also, I was slightly frustrated and slowed down by having to use the included hand tool instead of my Hoto Tools screwdriver.

Once built, the chair feels high-quality, the materials seem likely to last, and there’s no squeaking or creaking. So now the question remains, is the build time worth the comfort of the chair? I think it’s worth consideration.

Sihoo Doro C300 Pro V2: Design & Build Quality

The Sihoo Doro C300 Pro V2 is mostly a sleek, elegant white mesh, with a PU-coated armrest and a rigid frame. The chair itself is quite comfortable, all while looking very modern and clean. It’s not your average office chair, nor your average cheap Amazon home office seat. Nay, this is a high-brow, powerful-feeling office chair that feels like it belongs in NASA, not in a home office.

While using this chair, I haven’t noticed any wobble or shake, and I haven't had any concerns about base stability, rolling wheels, or leaning back. While this may not be the look that everyone wants, the comfort is hard to deny. I remember the first round of Sihoo Doro chairs that I tested. I was genuinely impressed by how comfortable the spaceship-like chair felt, even on long days.

The mesh seating provides a good balance of support and comfort. The seat doesn't feel like a hammock, which is always a good sign for more expensive chairs. In general, there aren’t any spots that feel cheap or plasticky. Which could be a bit shocking. Not because Sihoo has a bad rap, but because this chair has a ton of moving parts, and that many moving parts could easily result in squeaks, loose tolerances between parts, and so on. But again, what is fantastic is that this has not been the case with the C300 Pro V2 yet.

Another thing to note is that this is a massive chair. I’ve tested a lot of chairs, and some just feel robust, some feel quaint. This chair feels beyond robust. It feels like the difference between a RAM 1500 and a base Ford F-150, or an iPad Pro 13-inch with a Magic Keyboard vs an iPad Air with a thin folio.

Some of the chairs that I have recently tested and am currently testing, along with the C300 Pro V2, are significantly narrower and less… intense… for lack of a better term. Next to a smaller desk, say a 24-inch or even a 48-inch desk, this chair will look massive. But if you have a larger desk, perhaps in the 60-inch range or beyond, this chair will probably fit right in, depending, of course, on some other variables too.

Sihoo Doro C300 Pro V2: In use

I’ve had this chair back for about a week and a half after getting the replacement unit. So far, after several hours a day using this, I haven’t had any discomfort. It took me a little while to dial the chair in; with so many adjustable options, I kept wanting to make sure every setting was dialed in.

Personally, I see the benefit of the multi-functional armrests for some, but since I am not a gamer, I just keep them in the same general spot. But if you want to use this as an after-hours gaming chair or relaxation chair, too, you’ll be set.

The lumbar support is nice, and I do feel a good amount of support in my upper back when seated, too, though it doesn’t hit me at 6’1” exactly where I wish it did. But if you’re a tad shorter, it would probably be perfect for your lower back.

One thing I absolutely love on chairs like this, though, is the breathable mesh. I’ll say it time and time again: I run warm, so sitting in some of these very soft, non-mesh chairs I have, as comfortable as they are, I feel like I am sweating within a few minutes. With the mesh on the C300 Pro V2, though, I feel like my body can breathe even for long working sessions.

I’ve used this chair for intense writing sessions, leaning back a bit during virtual internal meetings with my team, more alert and focused in client meetings, and while working on project management and other tasks. Unless I am 100% locked in, which does happen pretty frequently, I am fairly fidgety. My leg is bouncing, my feet are moving, and I find myself twisting a little in my chair, even. So far, with all my movements, I haven't heard a creak or a squeak.

Sihoo Doro C300 Pro V2: Final verdict

At the end of the day, this is a spectacular chair when you sit in it. The hesitations come with the build time, the complexity, and the design language, but primarily because it’s a distinct chair. It doesn't blend in and takes up a lot of space. So, if you’re the kind of person who likes that, this may be a dream come true, but if not, then this may not be the chair for you, and that’s okay.

However, if you do want a more robust chair, if you have the space for it, and you want a chair that you can fiddle with to make fit your every possible position of work play rest and everything in-between, then this may just be exactly what you are looking for.
