Innovative seat cube system
Flexibly adaptable and can be used anywhere - the FLATCUBE.
Whether as effective promotional seating at your trade fair stand, as a must-have at your next event or as an environmentally friendly alternative - the FLATCUBE with its interchangeable covers is a master of customization, a lightweight for transport and a great deal of functionality.
With its versatile designs, the FLATCUBE can be optimally integrated and, if necessary, can also be staged in a striking way. Thanks to the innovative folding mechanism, transporting seating furniture is no longer a question of size, whether of muscles or loading areas. With the FLATCUBE, you can quickly offer space anywhere - or take it, linger and, when there's time, efficiently keep things tidy in the folded, slim version. And all this without the use of additional aids, but with the good feeling of having done something for the environment. This is because the FLATCUBE is made from recycled materials and is also recyclable, in addition to short CO2-saving delivery routes. The whole thing is tested, certified and awarded!
As a foldable seating cube, the FLATCUBE not only takes on new dimensions, but also shows us an unexpected form of efficiency and sustainability as seating furniture.

The FLATCUBE user benefits
Effortlessly miniaturized, easy to transport, efficiently stowed, sustainably produced

Convenient transportation due to small pack size
Easy to carry, hard to beat!
When quick and uncomplicated transportation is required for trade fairs or other indoor and outdoor events, the special strength of the seating cube comes into play. This is because the FLATCUBE has a patented folding mechanism that allows the seating cube to be folded down to a minimum, making it easy to transport. This is of course also due to the material used: lightweight yet robust. It is easy to assemble and disassemble. Folded up in its slim shape, it can be stored almost anywhere, ready to hand of course. This way, you can arrange rooms or public areas as you need them at any time.
Versatile application options on site
It can go anywhere! And it can do a lot!
Thanks to its robust, weatherproof material made from recycled plastic and the interchangeable parts, it is a long-lasting companion for any indoor or outdoor setting. It is used at trade fair stands or in art museums as well as at beach parties or concerts in the park. The locations are as versatile as the uses. It can be easily folded up and folded down again. If you want to flexibly furnish and transform your home or public spaces, from showrooms to lecture halls, the FLATCUBE is the perfect solution. And by the way: if something does break, it can be repaired easily and independently thanks to its replaceable parts.
Interchangeable seat covers as advertising space
Soft shell, hard core!
Do you want to combine function with aesthetics? Various interchangeable OEKO-TEX® certified covers, which are simply pulled over the robust body without any tools, not only provide a pleasant sitting experience, but can also be used as an effective advertising communication surface. It doesn't matter whether it is simply branded with a logo, informative or decorative, its 5 sides can be printed in any color. The seat covers are available in different surfaces and colors for an individual (seasonal) feel. If you should ever change your design or advertising concept, thanks to the FLATCUBE you don't need new room furnishings.
Environmentally conscious & sustainable consumption
For the sake of the environment
If you want to do something for the environment when buying a piece of seating furniture, the FLATCUBE is the perfect choice. This is because we demonstrably save CO2 emissions both in the choice of material components and in production and transportation. The environmentally friendly aspect is therefore not only due to the transport-friendly volume to which the seat cube can be reduced, but also to the sustainable production method and the choice of recycled and recyclable materials. One thing is certain: compared to conventional foam cubes, it can do more with far less material and is also environmentally friendly.
You won't regret this seat cube! So don't wait any longer:
