Office Chair with Linkage Function
The following three office chairs come with linkage functions:

Sihoo C300 Second-Generation Pro Ergonomic Chair: The linkage function of this office chair is mainly achieved through two core technologies. The Syncrole Lumbar-Back Gliding Technology can precisely fit the curves of the human lumbar and back, providing dynamic support to reduce fatigue from prolonged sitting. The DynaCore Full-Process Dynamic Tracking System enables the synchronized movement of the armrests, lumbar pillow, backrest, and headrest. When the user adjusts their sitting posture or moves their body, these four areas will adjust simultaneously, ensuring that the chair and the user remain in sync, following the body's rhythm and providing all-around support.
Hbada E3 4th Generation: Its linkage function is embodied in the "T-shaped Linkage Support System". This system provides linked support for the waist, neck, and shoulders, emphasizing a 3-zone adaptive lumbar pursuit design. The lumbar area features a wrap-around support with left and right wings that can rotate 40 degrees, accommodating users of different body types. The elastic traction system in the middle zone adjusts in real-time with lumbar movements, ensuring precise support for the waist and reducing lumbar pressure caused by improper sitting postures.
Qingxian Dynamic Ergonomic Chair Series: The linkage function of this chair is based on the Holographic Follow-up System, which was introduced with Qingxian's first product in June 2025. Through a precise design of 4 sets of linkages and 60 joints, it achieves millisecond-level linkage of the headrest, backrest, seat cushion, and armrests. The system can sense subtle changes in the user's body posture in real-time and automatically adjust the angles and positions of each support component, ensuring that all body parts remain in a comfortable supported state. This dynamic adjustment function is particularly suitable for users who need to frequently change their sitting postures, effectively enhancing comfort and health during prolonged sitting.
