Split-back Xiaomi Office Chair

On the Xiaomi Youpin platform, ergonomic office chairs with split-back (non-integrated backrest) designs mainly include the Moga S3 Plus Geek Edition and the Henlin Bravo Xuanxing ergonomic chair. Here are their specific features:

Moga S3 Plus Geek Edition
This office chair employs the VTS sliding and variable-track motion system. Its core design ensures that the lumbar support can continuously track the position of the waist during both upright sitting and reclining, providing dynamic support. The backrest and seat cushion are linked through a mechanical structure, forming an integrated support system. However, the lumbar support and backrest are not completely independent but work in tandem through a linkage mechanism. This design is suitable for users who require continuous waist support, especially during dynamic sitting postures (such as reclining for rest), where the lumbar support can automatically adjust its angle and pressure to reduce the sensation of the waist being suspended. Additionally, it is equipped with TrackMaster 6D armrests that support multi-directional adjustments, including forward/backward and left/right sliding, height adjustment, rotation, and angle locking, accommodating users of different heights and sitting habits, enhancing operational convenience.

Henlin Bravo Xuanxing Ergonomic Chair
This chair features a split-back structure with an S-shaped spine-hugging backrest design, paired with a double-layer adaptive lumbar support. The lumbar support can independently slide up and down by 5cm, allowing users to adjust its position according to their needs for more precise waist support. This design more closely aligns with the strict definition of a “split-back chair,” where the backrest and lumbar support are completely independent and do not interfere with each other. Furthermore, the chair offers three levels of rocking and reclining functionality (90-135°), suitable for lunch breaks or short rests; the 3D rotating armrests support multi-dimensional adjustments, and the 2D multi-dimensional headrest can accommodate the neck support needs of users of different heights. Overall, its split lumbar support design is more suitable for users who have clear requirements for waist support and desire the freedom to adjust the lumbar support position.

Exclusions to Note
Although the Xiaomi Commuter Backpack mentions a “split design,” it refers to the compartmentalization within the backpack and is unrelated to office chairs. The UE H8 dual-back linkage chair features an upper and lower dual-back integrated frame, where the backrest and lumbar support are linked through a mechanical structure, failing to meet the split-back requirement.
