High-End Office Chair Chassis
Mid-to-high-end office chair chassis mainly come in several types: single-spring, dual-spring, adaptive, fiberglass, and carbon-fiberglass composite spring plates.
Single-spring chassis: The front half of the usage experience is relatively easy, but the back half can feel more strenuous. This is because its travel is short, and the spring force distribution is uneven, making it easy to cause fatigue after prolonged use. Therefore, this type of chassis is gradually being phased out of the market or used in low-end products.
Dual-spring chassis: By adding an additional spring to assist in controlling the force, it effectively solves the problem of uneven resistance during reclining, significantly improving stability and providing a more comfortable sitting experience. Some companies have also independently designed it to include more functional adjustment options, such as adjusting the reclining force with a joystick and adjusting the seat depth to meet the needs of different users.
Adaptive chassis: It can automatically adjust the reclining force based on the user's weight, theoretically providing a more personalized usage experience. However, when the user's weight exceeds the normal range, its adjustment function may not be precise enough, significantly reducing comfort.
Fiberglass chassis (dual-fiberglass spring plate chassis): When the chair back reclines, the deformation ratio is small, and the reclining resistance is uniform, providing users with a smoother reclining experience. However, currently, there is a lack of unified standards for the production process of this chassis, resulting in significant differences in the experience of products from different manufacturers. This chassis technology is commonly used in high-end ergonomic office chairs abroad, but its research and development are challenging, with the difficulty and cost of research and development increasing exponentially with each additional degree of reclining angle.
Carbon-fiberglass composite spring plate chassis: It belongs to high-end chassis technology, offering an excellent reclining experience. For example, the flagship space chassis used in the Sihoo C500 second-generation ergonomic office chair applies this technology, providing users with an ultimate comfort experience.
Well-known chassis brands in China include Zhongtai and Yongyi, while internationally, there are brands like Donati and Boke. These brands have certain technical strength and market reputation in the research and development and production of chassis.
