Office Chair Drift Chassis
The office chair drift chassis is an innovative design aimed at enhancing the comfort and support of ergonomic chairs. It dynamically adjusts the linkage between the chair back and the seat cushion to address support pain points during reclining or leaning forward in traditional ergonomic chairs.

The 8-axis 1-core drift reclining chassis equipped on the ErgoTune Gold B Eagle achieves only a 1-centimeter upward movement of the seat cushion's front edge when the chair back reclines, through a precise mechanical structure. This design avoids issues such as leg pressing or heel lifting caused by excessive seat cushion movement in traditional ergonomic chairs during reclining, while ensuring the stability of the lumbar and neck support points. Its core advantage lies in the fixed position of the lumbar pillow during reclining, addressing the pain point of lumbar pillow displacement due to changes in the chair back angle in traditional ergonomic chairs during reclining, making it particularly suitable for users who need to recline for extended periods.
The pioneering drift load-relief chassis of the ErgoTune Gold E2 further optimizes the dynamic support experience. Through a multi-axis linkage mechanism, this chassis achieves the "three nos" effect of no heel lifting, no leg pressing, and no change in the support positions of the waist and neck when the chair back reclines. Its smooth reclining-to-the-bottom design reduces resistance when getting up, lowering muscle strain. Additionally, the chassis features a forward-leaning assistance function, guiding users to maintain correct posture by adjusting the angle between the chair back and the seat cushion, reducing pressure on the spine from poor postures such as arching the back or slouching.
The DriftSyncโข drift spring chassis of the Mogga R9 PRO Smart Ergonomic Chair focuses on optimizing support for forward-leaning scenarios. This chassis achieves synchronous forward movement of the chair back and the seat cushion through a spring structure, maintaining a "straight-spine forward-leaning" posture with a hip angle (the angle between the thighs and the torso) greater than 100 degrees. This design effectively disperses the pressure on the waist during forward leaning, avoiding lumbar fatigue caused by prolonged arching of the back, making it particularly suitable for users who frequently need to lean forward to operate a computer or read. Its dynamic adjustment mechanism can also automatically adjust the support force according to the user's weight, enhancing adaptability.
The common feature of these three types of drift chassis is the linkage adjustment between the chair back and the seat cushion through mechanical or spring structures, but with different focuses: the Gold B Eagle emphasizes reclining stability, the Gold E2 provides comprehensive support for both reclining and forward leaning, and the Mogga R9 PRO focuses on spinal protection during forward leaning. Users can choose the appropriate model based on their usage habits (such as the frequency of reclining for rest and the need for forward-leaning operations).
