Ergo AXIS™ - Control in every position.

The Ergo Axis ergonomic chair fully meets the requirements and complies with the Regulation of the Minister of Family and Social Policy of October 18, 2023, amending the regulation on occupational safety and health at workstations equipped with display screen monitors.

The Ergo Axis swivel chair is equipped with a gas lift and a backrest connected to the seat by a synchronous mechanism. In combination with the possibility of adjusting the seat and backrest height, the backrest tilt angle, and a properly contoured seat and backrest, it ensures full adaptation of seating conditions to the individual needs of the user.

Additionally, adjustable armrests, headrest and lumbar support, and the mechanisms used enable dynamic and ergonomic sitting, as well as assuming a reclined, comfortable and ergonomic body position, conducive to relaxation and maintaining proper posture.

The Ergo Axis ergonomic chair meets the following standards and holds a Certificate of Conformity for them:

PN-EN 1022:2024-04

PN-EN 1335-1+A1:2023-04

PN-EN 1335-2:2019-03

BS 5459-2:200+A2:2008

The Ergo Axis chair has increased durability for users weighing up to 150 kg and is adapted for continuous 24/7 work.

The headrest is 390 mm wide and 200 mm high, and its height and tilt angle can be adjusted, allowing the support to be perfectly adapted to the user's height and the natural curve of the cervical spine. Proper adjustment reduces tension in the neck and shoulders, which is crucial during long hours of computer work.

The headrest is equipped with 9 notches, which allow its height to be changed within a range of 90 mm, while the tilt angle is adjustable within a range of 60°. The large surface of the headrest, made of flexible, durable, and resistant mesh, mounted on a frame made of polypropylene reinforced with 25% fiberglass, provides multi-dimensional and comfortable head support, ensuring a high level of user comfort.

The backrest is made of flexible, strong and resistant mesh, mounted on a frame made of polypropylene with 25% glass fiber, ensuring stability and even load distribution. The backrest consists of two separate parts that are connected to each other and provide coherent support for the back and lumbar spine.

The backrest width is 495 mm, and 450 mm in the lumbar section. The backrest height is 560 mm and is adjusted together with the contoured lumbar section using 5 detents within a range of 50 mm. The backrest tilt angle is adjustable from 90° to 132° and can be locked in 4 positions.

The back of the backrest is mounted on a durable polished aluminum structure, with two arms extending downwards and connecting under the seat with the mechanism elements. The screws securing the backrest to the height adjustment part and the lumbar part are aesthetically hidden under a plastic cover.

The possibility of adjusting the backrest height allows it to be adapted to the user's height, ensuring proper support for the entire spine. The tilt adjustment allows you to change position during work, which improves circulation and reduces muscle fatigue.

In the Ergo Axis chair, the seat is made of flexible, durable, and resistant 3D mesh mounted on a frame made of polypropylene with 25% fiberglass added.

The seat width is 490 mm, 680 mm with armrests, and the depth is 510 mm. The seat depth can be adjusted within a range of 50 mm using a handle (dimensions: 80x30 mm) located just below the seat on the left side of the user, allowing for easy and ergonomic chair adjustment for the user.

 The seat height adjustment, ranging from 470-570 mm, is performed using the first handle (dimensions: 40x30 mm) located just below the seat on the right side of the user. The underside of the seat is a cover made of polypropylene with 25% fiberglass added, with a thickness of 3.1 mm, making it resistant to deformation.

The seat combines excellent functionality with an ergonomic form, ensuring high seating comfort even during prolonged work. Such a seat allows the chair to perfectly adapt to the user's physique, promoting comfort during many hours of sitting. The seat has a rounded front edge to reduce pressure on the thigh muscles and prevent the feeling of numbness in the lower limbs when adopting a forward-leaning body position (e.g., during manual writing).

Adjusting the seat height allows you to place your feet firmly on the floor, maintaining a knee angle of approximately 90°. This is the basis of an ergonomic position that supports proper circulation and reduces the load on the lower back. It also prevents nerve compression, muscle tension, and numbness in the legs and buttocks.

Seat depth adjustment allows the chair to be adapted to the user's thigh length. The appropriate distance between the edge of the seat and the knees prevents compression of blood vessels and improves sitting comfort.

The second lever, measuring 80x30 mm, located on the user's right side, is used to adjust the backrest tilt, allowing for comfortable and ergonomic adjustment without needing to lean forward.

The synchronous mechanism has 4 locking positions with backrest tilt adjustment ranging from 90° to 132°. The synchronous mechanism allows for simultaneous tilting of the backrest and seat in appropriate proportions. This keeps the body in an ergonomic position even when changing positions, increasing comfort and relieving pressure on the spine.

The tilt angle lock allows the backrest to be stopped in the desired position. This is particularly important during work requiring concentration, where a stable body position increases the precision of tasks performed. Proper adjustment improves weight distribution, increases comfort, and supports ergonomic pelvic alignment.

The knob located under the seat, in its center, is used to adjust the backrest tilt tension, which is adapted to the user's weight. This is an extremely important adjustment, as setting the tilt tension too high for lighter individuals (approx. 45 kg) causes leg muscle tension and nerve compression leading to pain. Conversely, heavier individuals (approx. 90-120 kg) require stronger tilt tension, as setting it too low will result in an unexpected maximum backward tilt and excessive tension in the front of the legs. The resistance force adjustment allows the pressure needed to recline the backrest to be matched to the user's weight and preferences. This ensures smooth and controlled movement, and the backrest provides stable support without the effect of a sudden tilt for heavier individuals or excessive resistance for lighter individuals.

The anti-shock mechanism protects the user from the backrest suddenly returning after the lock is released. This prevents the backrest from hitting the back, and the change of position is smooth and safe, increasing comfort and caring for the spine. To unlock the mechanism again and set the backrest in the desired position, lean back on the backrest and gently push it backward – this allows you to re-adjust the tilt angle to your needs.

The chair has armrests with a soft 3D adjustable surface made of polyamide with 30% fiberglass and polyurethane. The armrest pad is 260 mm long and 110 mm wide, tapering to 90 mm at the back. The armrests adjust in the following planes:

- up-down adjustment in 4 positions over a range of 70 mm

- front-back adjustment in 5 positions over a range of 65 mm

- left-right angle adjustment of the pad over a range of 24°.

The multi-plane adjustment of the armrests allows for proper forearm positioning and relieves shoulder strain. Correct positioning reduces neck tension and the risk of wrist discomfort.

The gas lift is a Class 4 lift, with a 100mm extension. It is made of a steel casing that can withstand an even load of up to 200 kg, ensuring stability, and the internal core of the lift is filled with compressed nitrogen with a purity of 99.7%, which guarantees smooth and precise seat height adjustment while maintaining maximum safety of use.

The total height adjustment of the chair, including seat, backrest, and headrest height adjustments, ranges from 1160-1390 mm.

The chair base is made of durable polished aluminum alloy, class 350#. The base can withstand a maximum static load of up to 1136 kg. The base itself has a diameter of 640 mm, and with the casters, a diameter of 700 mm. Five 60 mm diameter casters are attached to the base.

The ability to freely rotate 360° increases mobility at the workstation and reduces the need for torso twisting. This lowers the risk of spinal overload and improves the ergonomics of daily movements.

The chair has 5 nylon castors with a diameter of 60 mm with quiet 360° rotation. This type of castors reduces wear on surfaces such as parquet, panels, etc.

The mesh is designed for use in office buildings and public facilities, with high resistance to abrasion, light, and fire.
