Powerton ERGO JANA Office ergonomic chair, Green

Powerton ERGO JANA is an ergonomic office chair designed for comfortable seating throughout the workday. It supports the body‘s natural posture, helps reduce fatigue and unpleasant strain on the back, cervical spine and forearms, and is therefore a great choice for the office and home workspace. High comfort is provided by a seat made of quality cold foam with a noticeably rounded front edge, which makes long sitting more pleasant. The contoured backrest provides pleasant support especially in the lumbar area of the back, while durable materials ensure a long service life even with daily use. A practical advantage is also the cover made of waterproof fabric, which makes maintenance easier and better resists common office accidents.

Synchronous mechanism

The synchronous mechanism allows synchronization of the seat and backrest movement so that both parts move simultaneously at a 2:1 ratio. This means that when the seat moves one centimeter forward, the backrest moves two centimeters backward. This synchronous movement is adjustable and enables comfortable and ergonomic seating.

You can lock it in four positions. When using the synchronous mechanism, the backrest automatically adapts to your movement to provide optimal support for the back and cervical spine. It thus helps reduce fatigue that arises from sedentary work. At the same time, it prevents permanent static muscle tension by frequently changing body position thanks to active sitting while working at a computer.

Seat depth adjustment

Correctly adjusted seat depth allows you to sit with your heels on the floor to ensure proper spinal alignment and blood circulation in the lower limbs. If the seat of the Powerton ERGO JANA chair is too short, you will lack support for your thighs and it can lead to unergonomic sitting, which may cause back pain.

Conversely, if the seat is too long, it can lead to an improper distribution of body weight, which may cause discomfort and pain in the lower back, waist and hips. Therefore, seat depth adjustment is an important element for optimal ergonomics and comfort when sitting, especially for people of different body sizes.

Backrest height adjustment

It is important to find a backrest height that supports proper body posture and minimizes tension in the spine and neck. Positioning is done by moving the entire backrest with mechanical locking of the chosen position.

The control button is located on the lower edge of the backrest of the Powerton ERGO JANA office chair. By vertically moving the backrest you set the lumbar support to a suitable position for any body height.

Adjustable headrest

The height- and angle-adjustable headrest serves to support the head and neck. Its main function is to minimize tension and pressure on the cervical spine, which helps reduce pain.

The headrest allows you to adjust its position and tilt in relation to the chair seat, enabling individual customization of head and neck support.

Seat height adjustment

Adjusting the seat height of the Powerton ERGO JANA office chair is important for proper ergonomics and comfortable seating. It is necessary to minimize tension in the lower back and legs, thereby increasing productivity and comfort during work.

The correct seat height should allow your feet to be flat on the floor and your knees to be at a right angle. The chair‘s gas piston allows a height adjustment range of 7 cm, and you can lock the height in any position.

Adjustable 3D armrests

The adjustable armrests serve to support the arms and improve comfort. They allow adjustment in three planes - height, depth and angle. Height adjustment of the armrests allows you to set their height in relation to the chair seat, which ensures the correct position of the arms and shoulders.

Depth adjustment of the armrests allows you to set the distance between the armrests and the backrest of the Powerton ERGO JANA chair, which ensures the correct position of the arms and improves lower back support. Angle adjustment of the armrests allows you to set their angle relative to the chair seat, which ensures the correct position of the arms and shoulders and minimizes pressure on the wrists and elbows.

Czech quality

The Powerton ERGO JANA ergonomic office chair was manufactured in the Czech Republic. You can therefore fully rely on its quality and long service life.
