COSTA — FEATURES

Lightweight look, robust construction

Costa combines a minimalist line with a stackable, lightweight construction. The flexible backrest provides comfort without upholstery.

01 /04

Five base options

Four-legged, on castors, sled, bar stool, or four-star base — with rubber glides or castors. One seat shape, five frames to suit different spaces.

02 /04

Stackable for storage

Costa is stackable, which means less storage space and faster set-up of multi-purpose rooms.

03 /04

Flexible backrest

The backrest is flexible, so it does not need to be upholstered for comfortable, pleasant sitting. A steel frame provides a stable, durable construction.

04 /04

Choice of armrests

Costa is a stackable chair, suitable for multi-use spaces — training rooms, meeting rooms, classrooms and waiting areas.

Frequently Asked Questions

What distinguishes Costa from other ergonomic chairs?

Costa is a stackable conference chair with a clean, minimalist line. Ideal for projects where the same design has to cover meeting rooms, training rooms and waiting areas at once. The lightweight construction makes moving and storage easy, while the flexible backrest provides comfort without upholstery.

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.

Is Costa suitable for project orders?

Yes. Costa is a standard choice for meeting rooms, training rooms, waiting areas and multi-purpose spaces. For project orders, larger quantities and further information, contact us at sales@heka-interior.com.

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.
