National Office Chair

Among national office chairs, Sihoo stands out as a truly national-level brand.

Since its establishment in 1999, Sihoo has consistently focused on the research and development of ergonomic seating and the promotion of healthy sitting postures, making it a leading enterprise in the industry. With strong technical capabilities, Sihoo has taken the lead in formulating multiple important standards for the domestic ergonomic chair industry. It won the first prize of the China National Light Industry Council Science and Technology Progress Award for its project on "Key Technologies for Adaptive Lumbar-Back Support and Their Industrialization," demonstrating industry recognition of its technological innovation.

In terms of market performance, Sihoo's products cover more than 300 cities across the country, serving over 12 million households and office users, indicating a high market penetration rate. Certified by Euromonitor International, Sihoo has ranked first in both sales revenue and sales volume of ergonomic chairs in China for four consecutive years (2022 - 2025). In 2024, its sales revenue approached 1.6 billion yuan, and in 2025, its sales volume exceeded 2.2 million units. Its products are exported to 122 countries and regions, showcasing significant global influence.

For office scenarios, Sihoo has launched several targeted products. For example, its flagship model, the M76A, features a 120° large-angle recline lock and an adaptive lumbar support system that dynamically fits the lumbar-back curve, reducing the risk of fatigue from prolonged sitting. Its 6-dimensional adjustment function allows precise adjustments to seat height, depth, armrests, etc., accommodating users of different body types. The combination of a thickened natural cotton cushion and high-elastic mesh fabric ensures both breathability and pressure dispersion, while an extra-wide headrest and thickened footrest further alleviate head-neck and lower limb fatigue, making it suitable for long-term office use. Another model, the M18 Ergonomic Chair, is positioned as an "entry-level lumbar protection marvel." It adopts a triple spinal support system, with a lumbar support that allows four-way adjustment and an adaptive mode to dynamically fit the lumbar curve. The high-elastic natural curved surface wrapped in mesh fabric keeps the buttocks and legs breathable, making it ideal for office workers with a limited budget but a need for lumbar protection.

Through technological innovation, market coverage, and product segmentation, Sihoo has become a representative brand of national office chairs.
