A Chair's Anatomy: The Ergonomics of Anti-Gravity Office Seating (2024)

Sitting for extended periods is an everyday reality in many workspaces, which can lead to a dangerously sedentary working day. This makes office chair design a crucial element for both productivity and overall well-being. Ergonomic design takes into account the human body's needs, including posture, comfort, support, and health. A good ergonomic chair is adjustable, allowing for better control and customized settings that support the spine and promote a natural position for the body's joints. An even better ergonomic chair employs technology to accommodate all seating nuances—including occasional slouching, neck rest, and continuous hip movements, among others—, helping to maintain good body posture at all times.

The Sihoo Doro-S300 ergonomic chair is a prime example of this, as its design aims to defy gravity and redefine comfort. Designed and manufactured by Sihoo, it reflects the brand's commitment to offering healthy and comfortable ergonomic products.

As their flagship product, the ergonomic chair incorporates years of research, lessons, and technology. This chair offers one of the most advanced seating experiences with its key features: a premium mesh made of Italian velvet and DuPont TPEE for ultimate comfort, a dual dynamic lumbar support that supports the user's back, an ultra-wide and soft integrated headrest, and a unique mechanism made of aerospace-grade glass fiber plates. These features provide a weightless reclining experience and a sense of zero gravity.

The Seat: Shock-Absorbing and Soft

As you sit on the Sihoo Doro-S300, the first thing you'll notice is the premium cloud-like mesh material. This material is a unique blend of Italian velvet and DuPont TPEE, creating a highly elastic, durable, and soft surface that provides relief from pressure.

The chair's shock-absorbing suspension system is the next standout feature you feel. It comprises four springs beneath the seat cushion, effectively absorbing shock as you sit down. This eliminates the hard landing often experienced with other seat cushions, reducing the sudden force that can create discomfort. In summary, this system allows the chair to respond immediately to uneven loads from the seat and backrest, ensuring a uniformly comfortable experience.

The Backrest: Customizable Lumbar Support and Flexibility

Emphasizing the customizable and adjustable principles of ergonomics, the Sihoo Doro-S300's unique backrest is separate from the seat and individually caters to both the upper and lower back. An innovative, customizable dual-dynamic lumbar support is incorporated for the lower back. This feature includes omnidirectional springs that not only provide a broad support area for your lower back but also automatically adjust to accommodate different sitting positions and body shapes.

Given that people have varying body sizes, the dual lumbar support for the lower back can be adjusted to different widths and fine-tuned from 90° to 105° for an ideal fit. While the lower backrest remains fixed, the upper one can be adjusted to different heights to provide adequate support for the shoulders and neck. The innovative separation of the upper backrest and lower lumbar ensures that, irrespective of whether you're sitting upright, slouching, or using the prominent lumbar seating, your back is always supported.

The above features optimize good posture and fit within the chair for a smooth, effortless, and weightless reclining experience. It also features an industry-leading mechanism with an aerospace-grade glass fiber plate, a material also used in spacecraft. This design allows users of various body shapes to smoothly recline to deep levels, stop at any angle, and return to an upright position effortlessly.

Unlike conventional chairs that require the backrest to be locked at a desired angle, the Sihoo Doro-S300 allows for free reclining without the need for locking. This feature gives the chair an anti-gravity feeling, enabling users to maintain good posture while enjoying a weightless experience comfortably. Additionally, the chair's armrests automatically adjust in coordination with the backrest when reclining, ensuring various parts of your body remain relaxed. This feature prevents stress and enhances the overall seating experience.

The Armrests: Six Directions for All Sizes

Furthermore, the chair's armrests are adjustable in six directions, providing appropriate support to your arms, regardless of your height and sitting position. It also features a wide, soft headrest that contours to the curve of your neck, offering a spacious and comfortable support area. Finally, the seat cushion, resembling the curve of a waterfall, effectively maximizes the contact area while minimizing pressure on the thighs and hips for a more relaxing and comfortable sitting experience.

The chair's striking feature is the single-piece, shiny metal main structure on the back, connecting the Anti-Gravity Mechanism, dual dynamic lumbar support, and independent backrest. This structure is crafted from a single piece of aluminum alloy, fitting seamlessly into any space's design. Its exceptional design was awarded the "Excellent Product Design in Office Furniture" by the German Design Award 2023—a testament to its innovation.

The Sihoo Doro-S300's groundbreaking anti-gravity mechanism, innovative features, and aesthetics represent over a decade of expertise in ergonomics and engineering, delivering superior support and comfort.
