FAQs

Is this chair suitable for standard desk heights?

No, this chair is specifically designed for high-rise applications such as drafting tables and standing desks.

What is covered under the warranty?

The chair comes with a 5-year warranty on mechanical parts and a 2-year warranty on the foam and fabric.

What standards does the chair meet?

It is compliant with EN717-1, EN1335-1, and EN1335-2, and features Greenguard and REACH certifications.

Does it require professional installation?

No, the chair is designed for user-friendly assembly, though we recommend having a second person assist with alignment.

How do I maintain the recycled plastic material?

Use a soft, damp cloth with mild soap. Avoid abrasive sponges or strong solvents that could scratch or damage the plastic finish.

Can the auto-tilt be locked into place?

The auto-tilt function is dynamic by design to support constant movement; please check the manual for specific locking capability models.

Troubleshooting

Chair height will not stay fixed

Ensure the gas lift is correctly seated in the base; if it continues to slip, check the underside lever for obstructions.

Backrest feels too stiff or loose

The auto-weight tension control is automatic, but ensure the user is sitting fully back in the seat to engage the sensor correctly.

Squeaking noises during movement

Check all screw points and bolts to ensure they are fully tightened; a light application of silicone-based lubricant may be used on mechanical joints.

Pros and Cons

  • Advanced ergonomic adjustments for long hours at drafting tables
  • Environmentally friendly materials and certifications
  • Robust construction meeting EN international standards
  • Intuitive weight-sensitive tension controls
  • Sleek and modern design in a distinctive green finish

Cons

  • Limited to high-desk or standing desk applications
  • May feel unstable for users accustomed to low-profile seating

Setup, Compatibility & Care

To assemble the chair, ensure all components are cleared of packaging. Insert the gas lift cylinder into the base before attaching the seat assembly. Ensure all screws are tightened according to the included manual to maintain the EN1335 certification standards. Regarding care, regularly wipe down the frame and surfaces with a damp cloth to remove dust. As the chair is composed of recycled plastics and specialized fabric, avoid using harsh chemical cleaners that may degrade the materials. Periodically check the mechanical connections every six months to ensure continued stability.
