Operating Instructions: Adjustments
The FLEXISPOT OC8 chair offers multiple adjustment options to customize your seating experience for optimal ergonomic support.
1. Dual-Wing Dynamic Lumbar Support

Maintenance
Proper maintenance ensures the longevity and optimal performance of your FLEXISPOT OC8 chair.
- Cleaning: Use a soft, damp cloth with mild soap to clean the mesh and leather surfaces. Avoid harsh chemicals or abrasive cleaners. For the mesh, a vacuum cleaner with a brush attachment can remove dust.
- Casters: Periodically check the casters for hair or debris that may hinder smooth movement. Clean them as needed. The chair features smooth, silent, and anti-scratch wheels suitable for various floor types.
- Hardware: Every few months, inspect all screws and bolts to ensure they are tight. Re-tighten any loose hardware to maintain stability and safety.
- General Inspection: Check for any signs of wear and tear, especially on moving parts and upholstery. Contact customer support if you notice any significant damage.
