Frequently asked questions
What sets Fenix apart from other ergonomic chairs?
Designed in Slovenia with a focus on ergonomics, quality materials and sustainable manufacturing. Every chair passes through our own hands in Medvode, with in-house quality control before shipping.
How does the 7-day free trial work?
We deliver the chair to your address (office or home). You test it for 7 days in a real working environment. If it isn't right, we collect it free of charge. If you're convinced, you keep it and pay. No risk, no questions.
What sets Fenix apart from other ergonomic chairs?
Fenix is a proven ergonomic chair from our Slovenian production, now available in a limited clearance sale. The same comfort, the same quality and the same 3-year warranty as our other models — only the price is different. For more information, write to us at sales@heka-interior.com.
What warranty does Fenix have?
The 3-year manufacturer's warranty covers the mechanism, the gas lift and material defects. With our own production in Medvode, we supply spare parts even after the warranty expires.
Do you offer discounts for larger quantities or projects?
Yes. Volume discounts apply from 5 units up. For 200+ workstations (e.g. NLB Emona — 1,200 seats) we prepare a special offer with a custom configuration, free consulting, and an extended warranty. Send an inquiry or call +386 1 361 90 28.
Who is this chair for?
Ideal for anyone who spends more than 4 hours a day at a desk — developers, designers, architects, project managers and executives. The chair supports active sitting and reduces the load on the spine.
