AlzaErgo Chair Delta 2 Fabric grey
Premium Ergonomic Chair for Active Sitting
The AlzaErgo Chair Delta 2 Fabric office chair combines a premium design in grey, chrome, and aluminium with an exceptionally wide range of adjustment options. Thanks to the synchronous mechanism with an adjustable backrest tilt, a sliding seat, a height-adjustable backrest, a 3D headrest, and magic armrests, you can tailor it precisely to your body and sitting style. The fabric seat and headrest provide comfort for everyday use, complemented by a multi-layer filling that combines durable PU foam with a top layer of memory foam. A durable class 4 gas lift with an extended adjustment range allows comfortable use for users with a height of approximately 155–195 cm, while also ensuring the long life and high stability of the entire chair.
User height 155–195 cm
The extended lift of the gas piston allows for more precise seat height adjustment and better adaptation to different body types.
Weight capacity up to 130 kg
The robust construction and high-quality components ensure high stability and reliability.
Synchronous mechanism
Adjusts the seat tilt and height according to the backrest tilt, providing excellent ergonomic properties.
Magic armrests
The height, position, and angle of the armrests can be adjusted according to your current activity, providing optimal support for both work and rest.
Multi-layer seat
The combination of durable PU foam and a top layer of memory foam ensures optimal support, more even pressure distribution, and more comfortable long-term sitting.
Lateral rocking
Thanks to the lateral rocking of the seat with a range of ±6°, sitting is not completely static, which contributes to more natural movement and greater comfort throughout the day.
Sliding seat
The seat allows you to adjust the sitting depth to the length of your legs and ensure proper thigh support for users of different body types.
Adjustable backrest
The backrest can be height-adjusted in six levels with a range of 5 cm for an even better fit to your body.
Jacket Hanger
A removable hanger on the back of the backrest provides a convenient place to hang a jacket or coat.
Lumbar support
The ability to adjust the intensity of the support helps to ensure optimal support in the lumbar region according to individual needs.
A Memory Foam Seat Designed for Long Hours of Sitting
Long hours at the computer don't have to mean a stiff back or uncomfortable pressure on your seat. The seat of the AlzaErgo Chair Delta 2 Fabric has a multi-layer construction that combines durable PU foam with a top layer of memory foam, which adapts to the shape of your body and distributes pressure more evenly. The depth of the seat can also be adjusted by 5 cm, so you can easily ensure optimal thigh support. The result is greater comfort, better support, and less fatigue even during long working days. The fabric cover is pleasant to the touch, while also being highly resistant to everyday wear and easy to maintain.
The AlzaErgo Chair Delta 2 Fabric Adapts to Almost Any Body Type
The AlzaErgo Chair Delta 2 Fabric office chair offers a wide range of adjustments, allowing users from approximately 155 to 195 cm in height to find an ergonomic position. The extended height adjustment range is provided by a durable class 4 gas lift that accommodates a wide range of body types. The chair is equipped with a synchronous mechanism that coordinates the tilt and height of the seat with the tilt of the backrest. This provides better back support, promotes ergonomic sitting, and contributes to greater comfort throughout the working day.
Ergonomics Designed for Real-World Use
The backrest offers a wide range of adjustments to achieve optimal back support. The tilt can be adjusted from 105–140° and locked in four positions, so you can easily choose the ideal position for focused work or moments of rest. The backrest can also be height-adjusted in six levels with a total range of 5 cm to provide support exactly where you need it. After extending to the highest level, the mechanism automatically unlocks and the backrest returns to its lowest position. Its mesh design also promotes better air circulation and heat dissipation.
Lateral Movement for More Active Sitting
In addition to classic rocking, the AlzaErgo Chair Delta 2 Fabric also offers lateral seat tilt – the seat can move gently from side to side, naturally responding to changes in body position while sitting. This means that the posture is not completely static, leading to small micro-movements that resemble sitting on a balance ball. The lateral rocking promotes a more active way of sitting, greater engagement of the core muscles, and helps to reduce the feeling of stiffness during long periods of work. The ±6° rocking range is an ideal compromise between comfort, stability, and a sufficient range of motion.
Magic Armrests with an Exceptional Range of Adjustment
At first glance, they look like ordinary armrests, but they actually offer truly superior adjustment options. The magic armrests on the AlzaErgo Chair Delta 2 Fabric allow for height adjustment within a 10 cm range, as well as position changes by sliding them forward or backward. The armrests can also be swivelled up to 200°, while the upper support surface offers a 360° rotation. The wide range of adjustments makes it easy to find the optimal hand position and contributes to a more natural body posture. Correctly adjusted armrests also promote a more natural shoulder position and greater comfort during long periods of sitting. If you are not using them, you can simply rotate them to the back where they are almost out of the way.
Adjustable Lumbar Support for Individualised Back Support
The lumbar support allows you to adjust the level of support according to your individual preferences. You can adjust its height by moving the entire backrest, while the extension intensity can be regulated separately. Unlike common solutions, you are not limited to just a few fixed positions – the support can be locked in practically any setting within its range. This allows every user to set the exact support that suits them best.
3D Headrest and a Practical Jacket Hanger
Proper support for your head and cervical spine contributes to more comfortable and ergonomic sitting throughout the working day. That's why the 3D headrest offers height, depth, and angle adjustment, so you can easily adapt it to your body and preferred sitting position. On the back of the headrest, there is also a practical hanger for a jacket or coat. This keeps your clothing always at hand without needing a separate coat rack. The hanger is also removable, so you can take it off at any time or not install it on the chair at all.
Details You'll Appreciate Every Day
The synchronous mechanism uses a Cable Control system, which transfers the control of individual functions (seat height, tilt lock, etc.) via cables. This allows the control levers under the seat to offer smoother and more precise operation, contributing to a more pleasant user experience overall. The AlzaErgo Chair Delta 2 Fabric is equipped with 60mm PU castors that ensure quiet and smooth movement on carpets as well as common hard floors. If needed, the chair can also be fitted with other types of castors – you can find our selection here.
