Frequently Asked Questions
What distinguishes Costa from other ergonomic chairs?
Costa is a stackable conference chair with 18 basic base and backrest variations — one shape, endless combinations. Ideal for projects where the same design needs to cover meeting rooms, lecture halls, and waiting areas simultaneously. Its lightweight construction (from 5.8 kg) facilitates moving and storage, and its patented backrest attachment system allows for servicing without complete disassembly.
How does the 7-day free trial work?
We will deliver the chair to your address (office or home). Try it out for 7 days in your actual work environment. If it's not a good fit, we will pick it up at no cost. If you're satisfied, simply keep it and pay. Risk-free, no questions asked.
Can I custom-configure Costa?
Yes. There are 5 base versions available (four-legged, on castors, sled, bar stool, four-star base), 5 seat and backrest colors, 6 frame finishes (including polished chrome), three types of armrests (none, open, closed), a choice between exposed plastic and mesh for the backrest, and an optional upholstered version of the seat and outer backrest in all Heka fabrics (Urban, Nordic, Bora). A left or right writing tablet is available for the lecture hall versions. Over 100 possible combinations — contact sales@heka-interior.com for a project configuration.
What's the warranty on Costa?
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. Volume discounts apply for 5 or more units. For projects with 200+ seats (e.g., NLB Emona — 1,200 seats), we prepare a special offer with custom configuration, free consultation, and an extended warranty. Send an inquiry or call +386 1 361 90 28.
For which spaces and users is Costa suitable?
Costa is a conference chair for public and semi-public spaces: meeting rooms, lecture halls, educational institutions, waiting rooms, and restaurants. It has a weight capacity of up to 120 kg, and the CATAS certification confirms its suitability for intensive public use. The chair is stackable (up to 10 units for the four-legged version), making it easy to move and store between events. For prolonged sitting (more than 4 hours a day), we recommend Heka active chairs from the Ergoflex or Logic series.
