A chair can make or break your day. Comfort and posture are essential when it comes to any task that requires you to be seated for long stretches. However, regular chairs are just not up to the task and gaming chairs may be a bit too flashy and unaffordable for the workplace. Enter theSihoo Doro S300. With its subtle yet elegant design, and futuristic comfort features, the Doro S300 is the perfect chair for anywhere.
About Sihoo
Sihoo has specialised in ergonomic furniture and, over the past 12 years, has worked on technology that provides comfortable seating options that, in turn, improve productivity. With a team of over a hundred ergonomics experts and engineers, and an in-house research and testing institute, Sihoo’s products incorporate every possible parameter when it comes to your comfort at home or in the workplace.
Introducing The Sihoo Doro S300
The Doro S300 is Sihoo’s flagship ergonomic chair, with technology that has evolved over six generations. It incorporates every factor when it comes to seating posture, from your head right down to your thighs, to provide the most ergonomic and customisable position possible.
The Sihoo Doro S300’s offerings are truly gravity defying, thanks to the precision engineering and the carefully curated materials that go into it. It comes in two colour variants, with the black variant costing $899.99 and $909.99 for the white. If you head over to theSihoo websiteyou can get a discount of $100 on both of them.
The chair also comes with an extended 5-year warranty, where most other companies offer a 3-year warranty, and you test it out via a 30-day trial period.
Subtle Yet Futuristic Design
The Sihoo Doro S300 mixes cutting edge technology with elegant design to give you a chair that’s perfect for the office or home. It uses a blend of Italian velvet with DuPont TPEE for its mesh and is designed to look futuristic, yet understated, making it a brilliant addition to the office, unlike most ergonomic chairs that feature a flashy design.
This design has earned the Sihoo Doro S300 the2023 German Design Award for Excellent Product Design for Office Furniture.
Anti-Gravity Mechanism
This isn’t just a buzzword, but an intricately crafted system that provides top of the line comfort. The base of the chair features a pair of elastic plates made out of aerospace-grade glass fiber. This provides flexibility on an unprecedented scale, that can adapt to a wide range of height and weight. It also enables the backrest to recline at any position, without the need to lock into a specific angle, like most traditional ergonomic chairs.
Four-Spring Suspensions
Instead of using traditional hydraulic technology, the engineers behind the Sihoo Doro S300 opted to use a four spring mechanism that relieves pressure while sitting. Not only that, this specialised system allows the seat to adjust appropriately when the backrest is reclined, offering a more comfortable seating position. This system ensures that you get a cushioned landing when you sit, saving your back from any impact.
Dual Dynamic Lumbar Support
The most striking feature of the Sihoo Doro S300 is undoubtedly the wing-shaped lumbar support. Unlike most traditional chars that feature a cushion or a single pad, the Doro S300 features a specialised dual-winged lumbar support function.
This specially designed lumbar support system accommodates any sitting position thanks to its unique shape and a precision gas lift feature which allows for adjustment to the range of 90° to 105°. This ensures that no matter the height and proportions of the user, the Sihoo Doro S300 provides optimal support.
Upper Back Support
While most ergonomic chairs primarily focus on the lumbar region, the Sihoo has applied its expertise to every part of the Doro S300. The upper backrest of the chair can be adjusted in five independent positions, allowing for maximum support for a height range between 5 to 6.3 feet.
Coordinated Comfort
The lumbar support works in tandem with the upper back support to ensure maximum overall comfort for your entire back. Upon reclining, the upper back support, lumbar support, and suspension-supported seat seat cushion all move in a coordinated manner to ensure optimal support based on the degree of the recline.
6D Armrests
The Sihoo Doro S300 not only pays attention to your back. Armrests are just as important in a chair, whether it’s for office work or gaming. As with the backrest, the engineers at Sihoo have evolved the armrest of the Doro S300 beyond traditional functionality. Besides the regular functions you usually get in ergonomic chairs (up and down, back and forth, and swivel), the Doro S300’s armrests go in and out, swivel upwards and downwards, and move in tandem when the backrest is inclined.
Other Chairs By Sihoo
The Sihoo Doro S300 is the company’s flagship chair, offering a wide range of features, however, if you’re looking for a more budget friendly option, theDoro S100. It offers the same features as the S300 in the upper back and lumbar rests, but doesn’t include the four-spring seat cushion and 6D armrests. It features a similar overall design and is available on the Sihoo website at a discounted cost of $359.99.
