Aeris Numo Task

An office chair - as flexible as you are.

The design office chair Aeris Numo Task combines comfort with innovative technology. The patented Self Adjusting Motion Element (SAM) and kinematics, specially developed for the Aeris Numo Task , ensure a unique sitting experience. Together, the two technologies enable easy movements forward, backward and sideways - all while seated. The "SAM" is integrated in both the version with suspension strut and the version with column. You want even more movement?! With the variant with spring strut, the Aeris Numo Task offers the possibility to swing vertically. This up and down movement while sitting relieves the intervertebral discs and stimulates the blood circulation. The Aeris Numo Task is available in a variety of beautiful colors. The back cushion provides extra comfort. The ergonomic desk chair fits perfectly into any office or home office - whether at the dining table or at the desk.

Your summary
Recycled polyester (Cura, Gabriel)
Sitting comfortably within your four walls and doing something good for your back and the environment at the same time? Is that possible? Sure! The upholstery fabric of the Aeris Numo Task consists mainly of recycled post-consumer polyester (i.e. recycled PET bottles, among other things). This makes the design office chair sustainable, robust and easy to clean at the same time. In addition, the mottled look gives your home and your workplace a homely and modern touch.
Why Select
Capture is a lightly felted and multi-coloured wool fabric combining softness, stretch and strenght. It fuses light and dark colours to a refined melange pattern in subtle nuances, which add richness and depth to the design.

Aeris Numo Task - Super smooth on cloud 7.

Thanks to its innovative technology, the Aeris Numo Task gives you the feeling of sitting on cloud nine. The suspension strut variant enables an effective upward and downward movement while sitting, thus relieving the strain on the intervertebral discs. The patented kinematics technology underneath the seat shell ensures a wide range of movement forwards and backwards and promotes an upright sitting posture. Simply flexible and smooth at work what move.

Finally, a desk chair with the right attitude. Namely yours.

The patented Self Adjusting Motion Element (SAM) in the base of the Design Office Chair gives every user the same comfortable deflection to all sides - regardless of weight*. And because it's so well adjusted to you, we think: The Aeris Numo Task and you - It's a match.

A green office chair in many bright colours.

Old becomes new and looks good at the same time: The upholstery fabric of the Aeris Numo Task consists of 98% so-called post-consumer polyester, for example old plastic bottles and fishing nets. To prevent even more plastic from entering circulation, we have completely eliminated plastic from the packaging of the Aeris Numo Task . And by the way: our Numo Task chairs are "Made in Germany" and are assembled in our production facility near Augsburg. Of course with materials from a short supply chain.

* Optimized for a body weight of 45-120 kg.

Aeris Numo Task: One chair, many advantages

Upright sitting posture, all by itself

The patented Aeris kinematics underneath the seat shell follow your movements back and forth. This provides optimum support for an upright posture when sitting. The tilt of the backrest can be reduced using the locking function. For the greatest possible movement, we recommend the unlocked setting.

For a strong back

The Aeris Numo Task with suspension strut enables soft up and down movements while sitting. These movements promote blood circulation and get the circulation going. The vertical swinging also relieves the intervertebral discs so that back complaints can be prevented or counteracted.

A comfortable seating feeling

The flexible zone in the front edge of the design office chair adapts to your sitting position and prevents an uncomfortable feeling of pressure and blood congestion in the thighs.

One roll for all floors

The universal castors of the Aeris Numo Task are suitable for soft (e.g. carpet) as well as hard floors (e.g. parquet). In addition, the castors are self-braking. This prevents uncontrolled rolling away when sitting down. When seated, this braking effect is cancelled out by the load and you can simply roll from A to B.

Aeris Numo Task

Why the designer office chair is a must-have for your workplace

01 The Aeris Numo Task combines ergonomics with design

The Aeris Numo Task combines design with ergonomics. It is perfectly tailored to your needs and offers health benefits when sitting. The shell of the designer office chair with a suggested armrest and the upholstered seat are ergonomically shaped to support an upright and healthy sitting posture. In addition, the seat shell can be rotated 360 degrees, which gives you a perfect all-round view while sitting. The backrest of the ergonomic desk chair is equipped with slits that ensure good air circulation. If you choose the Aeris Numo Task with backrest cushion, it can be quickly and easily attached to the slots.

02 The design office chair brings movement into your life

Both versions of the designer office chair, the column and the suspension strut, enable slight movements in all directions while sitting. Without consciously noticing it, you easily change your sitting position and activate or relax individual muscle groups. In addition, the kinematics ensure that the seat shell follows your forward and backward movements. This keeps your back straight in the forward-leaning position or allows you to relax briefly by leaning against it. The Aeris Numo Task with suspension strut also enables movements in the 3rd dimension, namely up and down movements while sitting. This activates the muscles, relieves the strain on the intervertebral discs and can thus counteract back pain. The unique seating feeling of the Aeris Numo Task makes long periods of sitting at a desk much more pleasant. A long working day passes in a flash.

03 The desk chair fits perfectly in the office and home office

The Aeris Numo Task is flexible in use - whether at the desk in the office or as a home office chair. Even at the dining table in the kitchen or in the living room, the modern office chair fits in seamlessly thanks to its elegant and sleek design. Equipped with universal casters, the Aeris Numo Task can be easily rolled from A to B. The seat height of the modern office chair is infinitely adjustable and can thus be individually adapted to your body size and your workplace.

04 The Numo Task is sustainable and recyclable

With Cura, we have chosen an upholstery fabric made mainly from recycled post-consumer polyester. This polyester yarn is made from plastic waste, including old bottles and fishing nets fished from the sea. In addition, the ergonomic desk chair can be disassembled back into its individual parts and fed into the recycling process. All components of the Aeris Numo Task come from Europe. This enables us to keep delivery distances as short as possible. Of course, for the sake of the environment, we do not use any plastic packaging. The Aeris Numo Task is delivered to your home exclusively packaged in cardboard.

The Aeris Numo Task offers movement, active and dynamic sitting, comfort, sustainability, functionality and design - Now it's your turn! Configure now your design office chair for healthy and moving sitting and discover the limitless possibilities of the new Aeris Numo Task !

When we started the evolution of the Numo series two years ago, our challenge was to achieve an unprecedented seating experience. By merging the patented Aeris kinematics with the new SAM element, we created Aeris Numo Task a chair that makes you smile when you sit down.
