How does the 7-day free trial work?
We deliver the chair to your address (office or home). Try it for 7 days in a real working environment. If it doesn't suit you, we pick it up free of charge. If you are satisfied, keep it and pay. Risk-free, no questions asked.
Who is Stratos XL suitable for?
Yes. You can choose the fabric, frame color, base, and accessories. For larger projects, we offer additional configuration options and branding. Contact us at sales@heka-interior.com.

3-year manufacturer's warranty covers the mechanism, gas lift, and material defects. With in-house production in Medvode, we ensure spare parts even after the warranty expires.
Do you offer discounts for larger quantities or projects?
Yes. Quantity discounts apply from 5 items onwards. For 200+ seats (e.g., NLB Emona — 1,200 seats), we prepare a special offer with customized configuration, free consultation, and an extended warranty. Send an inquiry or call +386 1 361 90 28.
