5. Operating Instructions

5.1 Adjusting Chair Height and Angle

The Sleekform Tokyo Kneeling Chair features adjustable components to customize your seating experience:

• Seat Angle Adjustment: Locate the adjustment lever or knob beneath the seat. Loosen it to adjust the angle of the seat and knee pads. Find a position where your hips are open, and your back feels naturally aligned. Tighten the lever/knob to secure the position.
• Height Adjustment: The chair's overall height can be adjusted to suit your desk and body type. The height range is typically between 19 and 26 inches. Refer to the specific mechanism on your chair (usually a pin-lock or screw-type adjustment on the main frame) to raise or lower the chair. Ensure it is securely locked before sitting.

5.2 Proper Seating Posture

To maximize the ergonomic benefits of your kneeling chair:

• Sit with your shins resting comfortably on the knee pad and your buttocks on the seat pad.
• Allow your hips to open to an angle greater than 90 degrees, which encourages an upright spinal alignment.
• Utilize the backrest for additional lumbar support, ensuring your shoulders and neck are aligned.
• The handlebars can assist you in maintaining balance when getting in and out of the chair.

6. Maintenance

Regular maintenance will prolong the life and appearance of your chair:

• Cleaning: The chair's cushions are made from durable faux leather. For cleaning, use a damp cloth and mild soap for spot cleaning. Avoid harsh chemicals or abrasive cleaners.
• Frame Care: Wipe the metal frame with a soft, dry cloth to remove dust.
• Hardware Check: Periodically check all bolts and screws to ensure they remain tight. Re-tighten if necessary to maintain stability.
• Caster Wheels: Keep the caster wheels free of hair and debris to ensure smooth movement.

7. Troubleshooting

If you encounter issues with your Sleekform Tokyo Kneeling Chair, refer to the following common problems and solutions:

• Chair feels wobbly: Ensure all assembly bolts are fully tightened. Check that the chair is on a flat, even surface.
• Difficulty adjusting height/angle: Verify that the adjustment mechanism is fully disengaged before attempting to move. Clean any debris from the adjustment points.
• Casters not rolling smoothly: Inspect wheels for trapped hair or debris and remove them. Ensure the locking mechanism (if present) is disengaged.
• Discomfort during use: Adjust the seat angle and height to find a more comfortable ergonomic position. Take short breaks to stand and stretch, especially when first adapting to a kneeling chair.
