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.
