Clever Evo is an active ergonomic office chair built on a two-chairs-in-one principle: a smart mechanism activated by the user's body weight enables active sitting with constant micro-movement that strengthens muscles and encourages good posture, and when you need stability you simply lock the movement so the chair works like a classic ergonomic chair. One product gives you both active and classic sitting at once.

Clever Evo is part of the office-chair collection from Heka Interior, the office-furniture brand of Hit Preless d.o.o. from Slovenia. The furniture is made in Slovenia, and Hit Preless has produced furniture since 1986 and employs more than 80 people with its own production, logistics and installation. Our ergonomic solutions equipped over 1,200 workstations at NLB, and references also include Triglav and Volvo.

What is the Clever Evo active ergonomic chair?

Clever Evo is an active ergonomic office chair designed on a two-chairs-in-one principle. A smart mechanism activates with the user's body weight and enables active sitting through constant micro-movement that keeps muscles engaged and supports good posture. When you need steady sitting, you lock the movement and the chair works like a classic ergonomic chair. It therefore combines two sitting modes in a single product, without needing two separate chairs.

Why choose an active ergonomic chair instead of a classic one?

Prolonged static sitting strains the spine, causes neck pain and reduces concentration. Active sitting addresses these problems with constant micro-movement that keeps muscles engaged and improves circulation. With Clever Evo, the 3D-shaped seat moves together with the user, unlike classic chairs with a fixed seat. Ergonomists recommend regularly changing position while working, and an active chair encourages this by design.

How do the smart mechanism and movement locking work?

The Clever Evo smart mechanism activates automatically with the user's body weight, so there is no need for manual adjustment or calibration. When you sit down, the seat responds to your movements and enables active motion. With an innovative locking mechanism you can simply lock the movement, for example during a longer meeting or precise work, and the chair then works as a stable classic ergonomic chair.

  • Active mode — the seat moves with your body for micro-movement.
  • Classic mode — the movement is locked for stability.
  • Switching — tool-free, directly via the locking mechanism.

What ergonomic adjustments does Clever Evo offer?

Clever Evo offers a rich set of adjustments to fit different body types. It includes 4D adjustable armrests (height, depth, width and angle), height-adjustable lumbar support, adjustable seat depth via a sliding plate, and a 3D-shaped seat for optimal weight distribution. All of this lets you adapt the chair to your body and workplace. Learn more about correct setup in our guide on how to adjust an office chair.

What materials is Clever Evo made of?

The seat and headrest are upholstered in high-quality Puma fabric, available in black, dark grey and light blue. The backrest is made of black mesh fabric that provides good ventilation and prevents sweating during long working hours. The base is aluminium for stability and years of use, and the castors are rubberised, suitable for hard floors without damaging them.

Can Clever Evo be customised to company colours and logo?

Yes. For companies that need custom fabrics, colours or logos, we offer full personalisation to order. Because we make the furniture in our own production in Slovenia, we can match the chairs to a company's corporate identity and furnish offices consistently. Learn more about fabric and material choices on our materials page.

Who is the Clever Evo chair for?

Clever Evo is intended for anyone who spends long periods at a desk. It suits office workers who sit more than six hours a day and want to reduce strain on the spine, companies that need a standard ergonomic chair to furnish offices, the home office thanks to its compact form, and users with back pain, since active sitting relieves the spine and strengthens supporting muscles.

  • Office workers with long sitting hours.
  • Companies furnishing larger numbers of workstations.
  • Home office and remote work.
  • Users who want to relieve the spine.

How does Clever Evo work together with a sit-stand desk?

For a complete ergonomic workplace we recommend combining an active chair with a sit-stand desk. Switching between sitting and standing through the day further relieves the spine, while the Clever Evo active chair adds movement even in the seated position. Our sit-stand desk model CoreLift makes height adjustment easy, and whether the investment pays off is explained in our guide on whether a sit-stand desk is worth it.
