The Septa Chair, designed by etcetera, is a 3D-printed rocking chair made from 100% recycled polyethylene terephthalate glycol (PETG).
Design enthusiasts who visited OBJECT Rotterdam recently may have taken a moment to sit on this remarkable piece of furniture. And when you sit on it, you notice that you can not only rock in the ‘classic’ way, but also rock sideways.




As architects, the people behind etcetera, Ariane Stracke-Henderson and Rob Henderson, are always looking to engage in dialogue with their clients and the environment. In their design objects, this is expressed in the synergy between the production process, the material and the ergonomics.
This motion, combined with the playful, light-touch design, is the result of the 3D printing process carried out by the specialists at Nagami. 3D printing is like drawing a house, but without lifting your pencil from the paper. The production process must be carried out in one continuous movement. The Septa Chair is the result of this technological challenge and the desire to keep the carbon footprint of a new product as low as possible by using recycled materials.



And the experimentation continues, with research into 3D printing with metals and concrete, allowing this chair to also engage in dialogue with its surroundings in outdoor spaces.
The three models – in white, blue, and pink – are currently ‘on tour’. The next stop is Masterly – the Dutch in Milan, during Milan Design Week in April.
