Unveiling the Sihoo Doro S300: A Fusion of Style and Comfort in Office Seating

The Sihoo Doro S300 is undoubtedly one of the most striking, if not futuristic, chairs I’ve encountered in quite a while. Promoted by the Chinese brand as a ‘zero gravity’ chair, it’s likely engineered to make you feel like you’re floating in mid-air while you’re focused on composing an important email.

It’s wise to address that claim right away. Of course, no chair can genuinely make you float – otherwise, it wouldn’t serve as a chair at all. However, the Doro S300 comes remarkably close to giving you that sensation. There’s so much support in this chair that I have never experienced before, thanks to the actual suspension mechanism, alongside its numerous customizable features and sleek dual lumbar support. The feeling of relaxation, almost meditative, you get from using it is akin to settling into a cloud, truly.

This is not an overstatement, either. I’ve gone through my fair share of racing-seat style gaming chairs, and while the higher-end models like the Secretlab Titan Evo are comfortable, they don’t compare to the Doro S300. Everything on this chair is adjustable, from the seat itself to the armrests and back panels. This is a blessing in some respects, as you can tailor the Doro S300 to your heart’s content, although it can be troublesome in other cases. Even minor adjustments after returning to my desk caused the seat to move, while the armrests wouldn’t stay locked in place. They’re excellent for altering their angle or orientation, but they won’t stay secure for too long.

Regarding its adjustability, the Doro S300 offers up to 138 degrees of recline across three settings. For my use, I stuck to the middle setting to allow reclining without worrying about falling out of the chair. Along with that, there are those versatile 6D armrests that can move up and down, backward and forward, and even diagonally if you desire. The backrest is divided into two sections, with a broader top portion designed to support your head and shoulders, while the lower section is spring-loaded and adjusts the intensity of the lumbar support. The chair’s seat is also suspended on springs, which provides excellent cushioning when you first sit down.

This is a high-back chair that supports everything from your back to your arms exceptionally well, and I don’t miss the lack of a headrest, which some may find troublesome. I frequently used them in other chairs I’ve owned, possibly due to my less-than-perfect posture; however, the Doro S300 felt incredibly comfortable even without one. Being a mesh chair also means it’s breathable, and I didn’t find myself feeling too hot or sticky after using it for hours on end during the summer months when it tends to become particularly warm in our office. In all other scenarios, it’s been delightful to use.

Additionally, it’s exceptionally well-constructed with a combination of a thick metal frame, a soft mesh seat, and fibreglass components, making it one of the finest chairs I’ve encountered in terms of build quality. In the white colorway I have, it looks incredibly sleek. It is also fairly heavy, which can make it a bit cumbersome to move. Assembling the Doro S300 definitely requires two people.
