Powerton ERGO HANA Kancelářské ergonomické křeslo, Modré

The ergonomic chair Powerton HANA is designed to best meet your needs and to minimize the negative effects of sedentary work on human health. The benefits of an ergonomic chair include increased productivity and work efficiency, as you can focus on your work instead of suffering from discomfort and pain. 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. It has a padded seat and backrest, as well as adjustable armrests that help keep the arms in an ergonomic position and minimize tension in the shoulders and cervical spine.

The 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.

The base has an adjustable mechanism that allows for setting the stiffness of the seat and backrest according to the user's body weight. To adjust the stiffness of the mechanism, turn the control under the seat clockwise to increase stiffness or counterclockwise to decrease stiffness. If you weigh less than the average person, you will want to reduce the stiffness of the mechanism to move easily. On the contrary, if you have a higher weight, you 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.

It is important to find a backrest height that supports the correct body posture and minimizes tension in the spine and neck. The up-down system refers to the positioning principle without a control element, with automatic release in the upper position and locking in the lower position, while positioning occurs when the entire support moves upwards. By vertically adjusting the backrest, you can set the lumbar support to an appropriate position for every height.

Properly adjusted seat depth allows you to sit with your heels on the ground, ensuring the 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.

Adjusting 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 9 cm is enabled by the chair's gas lift, allowing you to lock the height in any position.

Armrests adjustable up and down provide comfortable support for the hands and improve posture while sitting. Their use can help prevent back, neck, and shoulder pain and improve overall well-being during work. They help keep the hands in an ergonomic position and minimize tension in the shoulders and cervical spine.
