How to use

Adjust the seat height using the lever under the seat so that your feet rest flat on the floor and your knees form approximately a 90° angle. Sit back so the integrated lumbar support aligns with the small of your back. Use the swivel function to turn smoothly between tasks without twisting your torso, and shift your seating position periodically to maintain circulation and reduce fatigue. Follow the included assembly instructions for safe setup and check that all fasteners are tightened before first use.

Usage recommendations

For optimal ergonomic benefit, combine correct seat height and lumbar positioning with regular short breaks and simple stretching exercises. Clean upholstery with a soft cloth and manufacturer-recommended mild cleaners; avoid aggressive chemicals to preserve the surface finish.
