Xihoo Office Chair

Xihoo (Sihao) office chairs come in multiple models, each with unique features. Here is a detailed introduction:

Sihao H300Pro: As a fully adjustable dynamic ergonomic chair, its core advantage lies in the four-way dynamic support rod technology, which can adapt to various sitting postures such as upright sitting, leaning forward, and slightly reclining. The lumbosacral region has tracking capabilities, enabling precise support by adjusting the distance between the lumbar support and the lumbosacral area. The chair offers a wide range of adjustment functions, including a seat height starting lower than most ergonomic chairs and adjustable by 8 cm, a seat depth adjustable by 3 cm forward and backward, a wide range of headrest height adjustments, and armrests adjustable in seven dimensions. During lunch breaks, it can be paired with a leg rest and lumbar stretching function. In terms of materials, it features a breathable four-way stretch mesh design in summer and can be switched to an air cotton cushion in winter, providing seasonal adaptability.

Sihao H300: Designed with the goal of "full posture, full body shape, and full scenarios", it uses a dual-dimensional support rod to achieve 5 cm electric adjustment up and down and 3 cm manual adjustment forward and backward, ensuring complete support for the lumbosacral area in different sitting postures. The headrest system is a 4D adjustable cloud-like design, supporting 6 cm of vertical adjustment, 8 cm of horizontal sliding, 55-degree rotation of the headrest surface, and 45-degree rotation of the头顶支架 (headrest top support, translated literally as there might be a more natural English term depending on context, perhaps 'headrest top bracket'), meeting personalized needs. The 7D linked mechanical arm armrests provide stable support for the arms while optimizing lumbar support comfort.

Sihao B300: With a light gray two-tone color scheme, it has a simple and versatile appearance suitable for both office and gaming scenarios. Its 4D micro-adjustment lumbar pillow supports four-level vertical adjustment, forward and backward extension, and floating adjustment, as well as left-right dynamic adjustment, providing comprehensive support for the waist. The contact surface uses mesh material, which disperses pressure by conforming to the body's curves, enhancing comfort during prolonged sitting.

Sihao Doro C300 Pro V2: As a fully body self-adaptive ergonomic chair, its core selling point is lumbar support. Through dynamic self-adaptive technology, it adjusts the support force in real-time according to body movements, maintaining comfort even during long periods of sitting.
