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.

Our configurator guides you step by step through the various options and customisation possibilities of the product. At the end of the configuration process, you can request a non-binding quote, download images and planning data and test the product directly in the room using augmented reality.

You can call up your personal configuration again at any time using your personal PIN code – just save it, come back later and make adjustments. Let's go!


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.

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.

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.
