Frequently Asked Questions
How does Master Q4 differ from other ergonomic chairs?
Master Q4 has two key advantages: 3D adjustable lumbar support (height and depth adjustable) and 4-position backrest lock (hence the Q4 designation). In most chairs in this price range, the lumbar support is only height-adjustable, without a lock. Master Q4 allows you to support your back exactly where you need it, and lock the mechanism in the desired position.
How does the 7-day free trial work?
We deliver the chair to your address (office or home). Test it for 7 days in your real work environment. If it doesn't suit you, we pick it up free of charge. If you are satisfied, keep it and pay. No risk, no questions asked.
Can I customize Master Q4?
Master Q4 is available in four colours of Bondai fabric: black, light grey, dark grey and blue. You choose the base between a chrome-plated five-star base or black PVC, and the chair is available with or without armrests. For more information, write to us at sales@heka-interior.com.
What's the warranty on Master Q4?
The 3-year manufacturer's warranty covers the mechanism, gas lift and material defects. We provide spare parts even after the warranty expires.
Do you offer discounts for larger quantities or projects?
Yes. Quantity discounts apply from 5 pieces onwards. For 200+ workstations (e.g., NLB Emona — 1,200 workstations), we prepare a special offer with custom configuration, free consultation, and an extended warranty. Send an inquiry or call +386 1 361 90 28.
Is Master Q4 suitable for tall or shorter people?
The Master Q4 is designed for users up to 120 kg and for most body heights. The seat height, tilt tension (according to weight) and 3D lumbar support (height and depth) are adjustable. The exact adjustment range is in the technical data sheet (PDF) above. For individual advice on suitability, call +386 1 361 90 28 or see the chair in person at the showroom in Medvode.
