Frequently Asked Questions

What's the difference between multi-tilt and standard tilt mechanisms? Multi-tilt allows independent back angle and seat tilt adjustment, plus forward tilt capability. Standard tilt mechanisms only recline the entire chair as one unit.

How do I adjust the air lumbar and thoracic support? Use the air pump bulb to inflate the lumbar or thoracic bladders. Pump air in to increase support depth, or press the release valve to reduce support.

Will this chair help my lower back pain? Proper ergonomic seating with adjustable lumbar support is essential for preventing and reducing lower back pain caused by poor posture. Consult with our ergonomic specialists or your healthcare provider for personalized guidance.
