Setup, Compatibility & Care
Assembly is straightforward but best performed on a flat surface to avoid damaging components. Ensure all bolts are tightened securely during the initial setup; it is recommended to check and re-tighten them after the first two weeks of use as the parts settle. To maintain the chair, vacuum the mesh fabric periodically to remove dust and debris. Use a damp cloth with mild soap for the seat cushion and plastic components, avoiding harsh chemical cleaners that may degrade the materials. Keep the gas lift cylinder clean of grit to ensure smooth height adjustments.
