Powerton ERGO JANA Office ergonomic chair, Grey

Ergonomic Chair Powerton JANAThe ergonomic chair Powerton JANA is designed to support the natural position of the body, thereby reducing pain and fatigue associated with long-term sedentary work.

Its main advantage is the ergonomic shape, which allows for the correct body posture and minimizes strain on the spine, forearms, and cervical spine.

It is suitable not only for work environments but also for home offices and for anyone who spends long hours sitting.

The chair is made from high-quality materials that ensure long-lasting durability and resilience.

Upholstery made of cold foam, along with the pronounced rounding of the front edge of the seat, maximizes comfort.

The contoured backrest provides significant support in the lumbar region of the back.

Synchro mechanismThe synchro mechanism allows for the synchronization of the seat and backrest movement, 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 five 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.Adjustment of mechanism stiffness according to body weight The base has an adjustable mechanism that allows the adjustment of the seat and backrest stiffness according to the user's body weight.

To adjust the stiffness of the mechanism, it is usually necessary to turn the control under the seat clockwise to increase stiffness or counterclockwise to decrease stiffness.

If the user weighs less than the average person, they will want to reduce the stiffness of the mechanism to move easily.

On the contrary, if the user weighs more than the average person, they will want to increase the stiffness of the mechanism to maintain the correct body posture.

It is important to correctly adjust the stiffness of the mechanism according to your own body weight to ensure proper ergonomics.

Stiffness set too high or too low can lead to back pain, neck pain, or non-ergonomic seating, which can cause health issues.Seat Depth AdjustmentProperly adjusted seat depth allows sitting with heels on the ground to ensure correct spine position and blood circulation in the lower limbs.

If the seat is too short, you will lack support for your thighs, which can lead to non-ergonomic sitting and may cause back pain.

On the contrary, if the seat is too long, it can lead to improper weight distribution of the body, which may cause discomfort and pain in the lower back, hips, and sides.

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 AdjustmentIt is important to find a backrest height that supports the correct body posture and minimizes tension in 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.

By vertically adjusting the backrest, you can set the lumbar support to an appropriate position for every height.Adjustable HeadrestThe 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 you to adjust its position and angle relative to the chair seat, enabling individual customization of head and neck support.

Seat Height AdjustmentAdjusting the seat height is important for proper ergonomics and comfortable seating.

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 armrestsAdjustable armrests are designed to support the arms and enhance 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 depth adjustment of the armrests allows you to set the distance between the armrests and the backrest of the chair, ensuring the correct position of the arms 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.
