FAQs
What is the maximum weight capacity for the M57?
The Sihoo M57 is rated for a maximum weight capacity of 150 kg.
Are the armrests removable during assembly?
Yes, but they are integral to the support structure of the backrest, so it is recommended to keep them attached.
Is the mesh seat durable?
Yes, the high-tensile mesh is designed for industrial office use and retains its shape well over years of use.
Can I lock the chair in any reclined position?
The chair features a tilt-lock mechanism that allows for locking at specific angles between 110° and 126°.
Does this chair require special tools to assemble?
All necessary assembly tools are included in the box.
Is the headrest height adjustable?
Yes, the headrest can be adjusted both in height and angle to provide comfortable neck support.
Troubleshooting
The chair feels wobbly or unstable.
Check all bolts under the seat mechanism and backrest. Ensure the gas lift is securely inserted into the base and seat chassis.
The tilt mechanism feels too stiff or too loose.
Locate the tension knob under the seat base. Turn it clockwise to increase resistance or counter-clockwise to decrease it.
The gas lift is not holding height.
Ensure the chair is not being overloaded beyond the 150 kg weight limit. If it continues to sink, check that the actuator is clean of debris.

Setup, Compatibility & Care
Assembly: The chair arrives in a flat-pack box. We recommend having a second person assist with attaching the backrest to the seat base, as the components are heavy. Ensure all bolts are tightened in a cross-pattern to maintain structural integrity.
Compatibility: This chair is designed for standard height desks. Its 150 kg weight limit makes it compatible with a wide range of body types.
Care Instructions:
- Mesh Maintenance: Vacuum the mesh periodically to remove dust and debris. If spills occur, use a mild soap solution and a soft cloth, then allow it to air dry.
- Base and Frame: Wipe the frame with a non-abrasive damp cloth. Avoid harsh chemicals that could degrade the finish.
- Hardware Check: Every 6 months, verify that the bolts under the seat and on the backrest are still tight to prevent wobbling.
