Some chairs come in one piece, while others require only a few main pieces to connect.
However, this one was exceptional in every way.
Most chairs with lumbar support have a single lumbar section that spans the width of the backrest.
This chair uniquely has two sections that hold your lower back in place on the left and right.
In short, these incredible Aerospace-grade materials make the Doro S300 stand out, even among other Sihoo chairs.
Besides the design, game changers are two main elements that stood out to me.
Firstly, the dual lumbar support provides lumbar support and helps align you with the center of the chair.
This helps to cradle your back in the best way possible.
Secondly, the spring seat support significantly improves over column-based or no suspensions.
The backrest and back support are among the best I have experienced.
It supports my lower back and mid-to-upper back very well.
The armrests on Sihoo chairs have always been a problem for me.
One more note, neither positive nor negative, is that this chair could have a headrest.
Lastly, the build quality of this chair has been fantastic over the last few months.
They have improved the armrests since my Doro-C300, but they are still too mobile for my liking.
Sihoo Doro S300: Final verdict
The Sihoo Doro S300 is a high-quality ergonomic office chair.
As mentioned, I have one frustration with this chair: the armrests do not lock in place.
Other than that, this chair has been incredible for my workspace.
It provides all-day comfort, supports me well, and looks gorgeous.
Especially for the money, this chair is worth considering for your workspace.
