Powerton ERGO JANA Office ergonomic chair, yellow

Powerton ERGO JANA is an ergonomic office chair designed for comfortable seating throughout the entire workday. It supports the body’s natural posture, helps reduce fatigue as well as uncomfortable strain on the back, cervical spine, and forearms, making it an excellent choice for both the office and home workspace. The high level of comfort is ensured by a seat made of high-quality cold foam with a distinctly rounded front edge, which makes prolonged sitting more comfortable. The contoured backrest provides comfortable support, especially in the lumbar area, while the durable materials ensure the chair’s long service life even with everyday use. A practical advantage is also the cover made of waterproof fabric, which makes maintenance easier and better withstands common office mishaps.

Synchronous mechanism

The synchronous mechanism enables synchronized movement of the seat and backrest, so both parts move simultaneously in 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 allows for comfortable and ergonomic seating.

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

Seat depth adjustment

A properly adjusted seat depth allows you to sit with your heels on the ground, ensuring the correct spinal position and blood circulation in the lower limbs. If the seat of the Powerton ERGO JANA chair is too short, you will lack thigh support and it can lead to non-ergonomic sitting, which may cause back pain.

Conversely, if the seat is too long, it can lead to improper distribution of body weight, which may cause discomfort and pain in the lower back, lumbar area, and hips. The adjustment of seat depth is therefore an important element for optimal ergonomics and comfort while sitting, especially for individuals with different body sizes.

Backrest height adjustment

It is important to find a backrest height that supports proper body posture and minimizes strain on the spine and neck. Positioning occurs when the entire backrest moves with mechanical locking of the selected position.

The control button is located on the bottom edge of the backrest of the Powerton ERGO JANA office chair. By vertically adjusting the backrest, you can set the lumbar support to an appropriate position for every height.

Adjustable headrest

The height- and angle-adjustable headrest is designed 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 its position and tilt to be adjusted relative 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 sitting. It is necessary to minimize tension in the lower back and legs to increase productivity and comfort during work.

The correct seat height should allow your feet to be firmly on the ground and your knees to be at a right angle. The height adjustment range of 7 cm is enabled by the chair's gas lift, allowing you to lock the height in any position.

Adjustable 3D armrests

Adjustable armrests are used to support the arms and improve comfort. They allow adjustments in three dimensions - height, depth, and angle. The height adjustment of the armrests allows you to set their height relative to the chair seat, ensuring the correct position of the arms and shoulders.

The armrest depth adjustment allows you to set the distance between the armrests and the backrest of the Powerton ERGO JANA chair, ensuring the correct arm position and improving lower back support. The angular adjustment of the armrests allows you to set their angle relative to the chair seat, ensuring the correct position of the arms and shoulders and minimizing pressure on the wrists and elbows.
