The Onemill Ergonomic Office Chair is designed for professionals, students, and gamers who spend extended periods at a desk and require enhanced spinal support. Its standout feature is the innovative dual backrest system that mimics the natural curvature of the spine to reduce fatigue, though users with very specific or narrow seating requirements should note that the fixed width of the dual-back structure may feel rigid compared to traditional single-piece chairs.

Yes, the armrests are designed to be flipped up, but they can typically be detached entirely during the assembly process if you prefer a completely open seating area.
With a 10cm gas lift and an adjustable 3D headrest, the chair is built to accommodate a wide range of heights, though individual comfort depends on torso length.
Yes, all necessary tools for the initial assembly are included in the packaging.
The tilt tension knob is located underneath the seat. Turn it clockwise to increase resistance and counter-clockwise to make reclining easier.
No, the lumbar support is integrated into the backrest design as part of the adjustable system.
Check if the gas lift cylinder is fully engaged with the seat base or if there is debris inside the mechanism.
Re-tighten the mounting screws that connect the dual backrest to the main frame of the chair.
Clear any carpet fibers or debris that may have wrapped around the wheel axles.
Assembly of the Onemill Ergonomic Office Chair is straightforward, utilizing the included 10cm gas lift mechanism for height adjustment. Ensure all bolts are tightened securely during the initial build to prevent squeaking. For maintenance, vacuum the mesh backrest periodically to remove dust accumulation, and wipe the foam seat with a damp cloth and mild soap to maintain hygiene. The flip-up armrest design makes this chair compatible with most standard-height office desks, but verify your desk clearance before purchase if you prefer to tuck the chair fully underneath. Avoid using harsh chemical cleaners on the mesh, as this can degrade the fibers over time.
