Sihoo Doro C300 Pro Chair Review

The Sihoo Doro C300 Pro ergonomic chair is designed to offer top-tier comfort and support for a wide range of users. Thanks to its customizable aspects, this chair supports weights of up to 300 lbs and user heights from 5’ to 6’3”. It’s a looker, too, boasting a more futuristic exoskeleton aesthetic that is tastefully eye-catching in modern office settings. After spending two weeks sitting in the chair for both my office job and PC gaming time, it’s time for my review.

Speedy build

The build process is simple enough, as highlighted in the video above. As is always the case with building chairs like this, I’d recommend setting aside more than enough time for the process. I’d also suggest building it in the room where it is staying, as these chairs can be tricky to move from room to room.

When it comes to ergonomic satisfaction, the Doro C300 Pro offers a range of features designed to promote healthier posture and more comfortable seating.

Comfort and support

The dynamic lumbar support, which automatically adjusts to the user’s spine, is a thoughtful addition designed to reduce the need for constant manual adjustments. Paired with the flexible backrest, which provides consistent support as you move, this feature is geared toward keeping users comfortable during extended periods of sitting. That said, some may find the lack of manual depth adjustment for the lumbar support a limitation, especially if they prefer a more tailored fit.

The chair’s adaptive design aims to accommodate users between 5′ and 6’3″, which is a generous range, though those on the edges of this spectrum might not find the fit perfect. I’m 6’7”, meaning that I’m one of the outliers who might not be able to achieve an ideal fit.

The spacious cushion is a welcome feature, particularly for larger individuals, and the adjustable seat depth adds another layer of personalization. However, the comfort may still depend heavily on individual preferences.

A new dimension

The 6D adjustable armrests are a standout feature in theory, allowing movement in nearly every direction to suit different activities. They perform well for most uses, but the lack of a locking mechanism can be a drawback, as they tend to shift unintentionally with movement. This can make the otherwise versatile armrests feel frustrating at times.

Adjustments to the chair are made simple with a single-handle mechanism that manages height, tilt, and seat depth. It’s an efficient system, though it might take some trial and error to get everything just right. The headrest, while adjustable in multiple directions, can feel slightly clunky, particularly when it clicks loudly during repositioning.
