The intervertebral disc office chair

The HARA CHAIR, model ZEN-LS, combines dynamic sitting with an integrated lumbar support. The patented seat meets all the requirements placed on an ergonomic office chair. This ergonomic office chair offers optimal sitting comfort over a longer period of time. Even after twelve hours you are still sitting comfortably. The concept - active sitting - makes it possible. The divided seat is flexible, adjusts itself automatically and adapts itself optimally to the angle of the pelvis. The ergonomic shape supports the lumbar spine as well as the shoulders and thus prevents tension.

Who is the ZEN-LS model suitable for?

This office swivel chair with the built-in lumbar support is suitable for everyone who sits a lot and wants to support their lumbar spine. In the case of a strong hollow back or after a herniated disc, this office chair primarily relieves discomfort in the lower back. With a pillow or a rolled up towel in your lower back, you can test for yourself on a standard office chair whether the ZEN-LS is the right office chair. The height-adjustable backrest of the ZEN-LS can be optimally adjusted to the lumbar area. The seat is 50 centimeters wide and 50 centimeters deep. For smaller people, HARA CHAIR also offers shorter seat cushions with a seat depth of 45 centimeters. And even one-95-meter people can still drop comfortably. The frame is built to be very stable, provided that they weigh no more than 120 kilograms. The ergonomic seat height can be adjusted from 43 to a maximum of 60 centimeters.

What distinguishes the HARA CHAIR ZEN-LS?

The split seat enables dynamic sitting. In contrast to office chairs with a rigid seat, the movable seat modules from HARA CHAIR avoid any pressure. This relieves the load on the spine and tailbone, protects the intervertebral discs and promotes blood circulation in the buttocks. Sleeping legs are a thing of the past with this office chair. Many extras ensure comfort. A coat hanger is integrated in the backrest on which you can hang your jacket, handbag or backpack. The extra long, height-adjustable headrest can also be removed if necessary. The large 50-millimeter castors are standard at HARA CHAIR, so that the office swivel chair can be easily moved even on uneven surfaces.

What versions are there?

The ZEN-LS model is available in black and seven other colors (petrol 02, anthracite gray 03, orange 04, navy 05, bordeaux 06, grass green 08, red 00R). The cover made of polyester fabric is very robust and has breathable ventilation openings. A special foam is processed in the backrest and seat, the air-conditioning slats of which have a heat-regulating effect and dissipate humidity. The user always feels comfortable.

What are the alternatives?

If you don't have back problems but want to prevent complaints, an office chair for dynamic sitting is recommended (see model NIE or NWL). In the case of intervertebral disc problems or a slight hollow back, a health chair with a light lumbar support is recommended, depending on the body weight (see model ZEN, CAE).

How can I avoid static electricity?

You will receive an anti-static chain with your office chair. You hang this chain on the base so that it touches the floor. The antistatic chain is only required for certain floors, shoes and work with sensitive electronic components. It prevents possible electric shocks when sitting down on the office chair.
