Frequently Asked Questions
What makes the Dune High different from other ergonomic chairs?
Designed in Slovenia with a focus on ergonomics, high-quality materials, and sustainable manufacturing. Each chair is configured to order—from the fabric and frame color to the type of base.
How does the 7-day free trial work?
We deliver the chair to your address (office or home). Try it for 7 days in your actual work environment. If it's not the right fit, we will take it back at no cost. If you're convinced, you keep it and pay. No risk, no questions asked.
Can I customize the high-back Dune?
Yes. You can choose the fabric, frame color, base, and accessories. For larger projects, we offer additional configuration and branding options. Contact us at sales@heka-interior.com.
What is the warranty on the Dune High?
The 3-year manufacturer's warranty covers the mechanism, gas spring, and material defects. With our in-house production in Medvode, we provide spare parts even after the warranty expires.
Do you offer discounts for larger quantities or projects?
Yes. Quantity discounts start from 5 items. 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.
Who is this chair suitable for?
Ideal for those who spend more than 4 hours a day at a desk — programmers, designers, architects, project managers, and executives. The chair supports active sitting and reduces strain on the spine.
