Office swivel chair for multi-user workstations

Self-adjusting swivel chair for multi-user workstations

se:flex is a must where multi-user workstations prevail. Thanks to the intelligent automatic weight system, it is able to adjust automatically to all users. At the same time, the backrest can follow every movement of the user, resulting in maximum freedom of movement and healthy sitting in all positions.

Design your own unique Sedus product – after all, maximum comfort requires customised solutions.

As diverse as its users

Freedom of movement designed the way you like it. How much advanced technology se:flex embodies is not visible at first sight. What is obvious, however, are the light, flowing shapes and the dynamic look. se:flex is as clear-cut in terms of its equipment and colour versions. The distinct design allows it to fit seamlessly into any modern office environment.

Classic

The polymer frame is available in either black or light grey.

Glossy

In addition to the black or light grey polymer version, the base is also available with a polished aluminium finish.

Moving

The black castors are available in two versions for hard and soft floors.

Furniture standards

The 4D armrest and comfort seat configuration of se:flex comply with the new DIN EN 1335-1:2023 Type A office chair standard. The configuration meets the highest demands, is state of the art and fulfils the requirements for a diverse range of users with different needs.

Versatile

With its various mesh membrane and slim upholstery colours, se:flex can be customised in a variety of ways.

Single-coloured

The light, transparent mesh membrane of the backrest is available in six different colours. The front and rear differ only in terms of their structure; the colours are the same.

Two-coloured

The colours and upholstery fabrics for the front of the slim upholstery can be freely selected from the Sedus fabric collections. Anthracite colours are always used for the rear.

Perfectly designed down to the last detail

Tuned for multi-user workstations – and individual needs. With intelligent features and an extensive range of basic options, the se:flex is optimally tailored to the requirements of smart working environments. In addition, se:flex offers a wide range of configuration options to make it even more convenient to use and easy to adapt it to individual needs.

More comfort

Instead of the innovative mesh membrane, the backrest can also be equipped with slim upholstery for enhanced comfort.

Flexible

The backrest follows the lateral movements of the user flexible in all directions and offers optimal support.

More support

The optional comfort lumbar support features a flexible filling to increase the individual ergonomic comfort level.

Three-dimensional

The freely adjustable armrests can be intuitively moved forwards and backwards as well as rotated to the inside and outside.

Within reach

The adjustment buttons of the sliding seat and of the armrests are placed in such a way that they can be used easily.

More pleasant

se:flex can be combined with a comfortable neck support and with a useful clothes hanger – ideal for changing workstations.

That's why: se:flex
