Ergonuma CARISMO™ - Style that supports.

The ergonomic Ergo Carismo 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 equipment.

The Ergo Carismo swivel chair is equipped with a gas spring and a backrest connected to the seat by a synchronous mechanism. In combination with the ability to adjust the height of the seat and backrest, the angle of the backrest, and appropriately 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 correct posture.

The ergonomic Ergo Carismo chair meets the following standards and has a Certificate of Conformity for them:
PN-EN 1022:2024-04
PN-EN 1335-1+A1:2023-04
PN-EN 1335-2:2019-03

The chair has a load capacity for users weighing up to 110 kg.

The headrest is 320 mm wide and 165 mm high, and its height and tilt angle are adjustable. The headrest is equipped with 9 notches, which allow its height to be adjusted within a range of 90 mm. The tilt angle can be adjusted within a range of 54°.

The large surface of the headrest, made of flexible, durable, and resistant mesh mounted on a polypropylene frame reinforced with 25% fiberglass, provides multi-dimensional and comfortable head support, ensuring the highest level of user comfort.

The height and angle adjustment of the headrest allow for perfect customization of support to the user's height and the natural curvature of the cervical spine. Proper adjustment reduces tension in the neck and shoulders, which is crucial during long hours of computer work.

The backrest is made of flexible, durable, and resistant mesh, set on a frame made of polypropylene with 30% fiberglass, ensuring stability and even distribution of load. The back of the chair's backrest is mounted on a durable structure made of polypropylene with 30% fiberglass, whose two arms extend downwards, connecting under the seat with the mechanism and armrest components. The screws fastening the backrest to the height-adjusting part of the backrest and the lumbar part are covered by an aesthetic plastic trim.

The width of the Ergo Carismo backrest is 480 mm, and its height is 600 mm. It can be adjusted in height, together with the contoured lumbar support, using 4 detents within a 30 mm range. The ability to adjust the backrest height allows it to be adapted to the user's height, ensuring proper support for the entire spine. In the mesh backrest, there is an aesthetic plastic element measuring 170x20 mm, which defines the lumbar support. This element connects to the rear part of the frame that adjusts the height of the backrest and lumbar support.

The backrest tilt angle is adjustable from 90° to 130° and can be locked in 4 positions.

The tilt adjustment allows changing position during work, which improves circulation and reduces muscle fatigue. The adjustable lumbar support supports the natural curve of the lower spine. The ability to set its height helps prevent back pain and strain resulting from prolonged sitting.

The ergonomically contoured seat is made of high-quality cast polyurethane foam (polyurethane foaming technology in molds) with a density of 55 kg/m³ and a thickness of 69 mm, covered with durable and resistant upholstery. The foam molding process at high temperature and the use of flexible material guarantee a uniform structure without empty spaces, which translates into high durability and resistance to deformation. The foam does not require the use of glue or formaldehyde, making it safe for health and environmentally friendly. The underside of the seat is a cover made of polypropylene with 25% fiberglass, with a thickness of 3.1 mm, making it resistant to deformation.

The seat has a rounded front edge to reduce pressure on the thigh muscles and prevent numbness in the lower limbs when maintaining a forward-leaning body position (e.g., during manual writing).

The width of the seat is 510 mm, with armrests 700 mm, and the depth is 510 mm. The seat height adjustment range of 500-600 mm is performed using a lever located just below the seat on the right side of the person sitting. This adjustment allows the feet to be placed firmly on the floor, while maintaining a knee angle of approximately 90°. This is the basis of an ergonomic position that supports proper circulation and reduces strain on the lower back. It also prevents nerve compression, muscle tension, and numbness in the legs and buttocks.

The seat also has a depth adjustment of 45 mm, using a lever located under the seat on the left side of the person sitting, which allows for easy and ergonomic adjustment of the chair to the user. This 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 seat combines excellent functionality with an ergonomic form, ensuring high sitting comfort even during long-term work.

The lever located to the user's left is used to adjust the recline of the backrest, allowing the function to be adapted conveniently and ergonomically, without the need to lean forward. The synchronized mechanism has 4 locking levels with backrest recline angle adjustment ranging from 90° to 130°. The synchronized mechanism allows the backrest and seat to recline simultaneously 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 selected 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 elongated ergonomic knob located under the seat on the right side 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 backrest tilt tension too high for light individuals (approx. 45 kg) causes leg muscle tension and nerve compression leading to pain. In contrast, heavier individuals (approx. 90-120 kg) require stronger tilt tension, as setting it too low will cause an unexpected maximum backward tilt and excessive tension in the front of the legs. Adjusting the resistance force allows you to adapt the pressure needed to recline the backrest 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 a heavier person or excessive resistance for a lighter person.

The anti-shock mechanism protects the user from a sudden return of the backrest after releasing the lock. This prevents the backrest from hitting the back, and position changes are 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 against the backrest and gently push it backward - this allows you to readjust the recline angle to your needs.

The chair features 3D adjustable armrests with soft surfaces, made of polyamide with 30% fiberglass and polyurethane. The armpad length is 260 mm, and its width is 110 mm, tapering to 90 mm at the back. The armrests are adjustable in the following planes:

- up-down adjustment in 5 positions within a range of 70 mm

- front-back adjustment in 4 positions within a range of 45 mm

- left-right angle adjustment of the armpad within a range of 24°.

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

The gas lift is a Class 4 lift with a 100 mm stroke. 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 chair height adjustment, including seat, backrest and headrest height adjustments, is within the range of 1160-1395 mm.

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

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

The armchair has 5 nylon castors with a diameter of 60 mm with silent 360° rotation. This type of castor reduces wear on surfaces such as parquet and laminate flooring.

Both the mesh and the fabric are designed for use in office buildings and public facilities with high resistance to abrasion, light and fire.
