Sihoo Doro C300 Pro office chair review

I’ve tested quite a few office chairs in the Sihoo Doro range, including the S300, S100, and the C300, and now, the C300 Pro – an upgrade on the former. So, opening up the Sihoo Doro C300 Pro, I had a good idea what I was in for.

By now, all the box openings feel the same, and the lumbar support in the C-lineup and the mesh across the Doro line-up feel the same. It’s all great. The one thing I keep getting hung up on for the otherwise fantastic chair is the flagship 6D armrests. Perhaps I lean more on my armrests than most; possibly, I am too particular, or maybe I am just the vast minority. Regardless, my team and I have found these armrests too mobile, making them challenging or frustrating to use rather than a benefit we desire.

What makes that sad to type is that the rest of the chair is excellent outside the armrests. It feels like a more budget-friendly version of one of my all-time favorite chairs, the OdinLake Ergo Plus 743. And that’s no small statement.

Sihoo Doro C300 Pro: Unboxing & first impressions

Like the other Sihoo chairs I tested, the Doro C300 Pro was no different. It came well packaged, with the necessary tools and that pair of white gloves I should wear but never do. Of course, there are instructions and packing material to help ensure that the parts don’t rub against each other, causing damage.

The materials are excellent, the mesh is comfortable, the frame is solid, and the ergonomics help and work well rather than feeling gimmicky or over/underdone. Right away, I got working on adjusting my settings to make this chair perfect. Then my arms pushed on the armrests, and I realized they were the same style as the armrests that have driven me nuts for a while now, but it does feel a bit better. Sihoo listened and tightened up the armrests to avoid unwanted tumbles.

Sihoo Doro C300 Pro: Design & build quality

The Sihoo lineup of chairs is always built well. The base is sturdy, and the mesh is durable and comfortable. Even after having a few Sihoo Doros in rotation with my team for years now, they are holding up quite nicely and are still loved.

The mesh material that most of the chairs are made from promotes easy airflow, allowing warmer individuals like myself to stay cool throughout the day (I used to get so warm sitting in those classic leather office chairs).

This chair’s design is also sleek, and it looks good in a home office setup, a co-working setup, an executive suite, or anything in between.

Sihoo Doro C300 Pro: In use

My team and I have had this chair in our rotation for 160 days at the time of writing this. It’s crossed between a couple of members and has landed with one individual who is 6’4″, about 250lbs and fairly muscular. He absolutely loves this chair and how comfortable it is for him. Normally, chairs that fit his height and weight are not meant for his build type, so he loves being able to fit in it comfortably and pull the desk chair arms in and not have them too wide. So far, he has not had any tumbles, which is a big win.

During my time using the chair, I noticed that these armrests seem to be a bit tighter, though I prefer less movement all around, maybe I’m a purist. I’ve worked entire days sitting in this chair for hours on end without needing to adjust, move around, or wish for another chair. Which, is saying quite a bit since I have some pretty remarkable chairs I get to use.

I feel like this chair can adjust for pretty much any body type due to all the adjustments available. I have actually been able to put this to the test with my team, ranging in weight and size pretty dramatically. It might take some time to adjust and fine-tune the chair to individual preferences. However, for someone using this chair in their personal workspace, or for those who aren’t concerned about having it perfectly customized in a co-working environment, this is not a significant issue at all.

Sihoo Doro C300 Pro: Final verdict

The Sihoo Doro C300 Pro combines ergonomic features with a luxurious feel while remaining affordable. It has dynamic lumbar support, great adjustability and high weight capacity, making it great for nearly any body type. While I personally don’t love the ultra-adjustable armrests, that’s a small note on this otherwise solid ergonomic chair.
