A classic silhouette with modern ergonomics

The Zeph Side Chair brings a new level of comfort and functionality to side chairs, offering the research-backed ergonomics of a task chair in a contemporary side-chair design. A unique hybrid with a range of uses, it works as well in individual work and small group settings as it does in educational settings. The advanced yet simple design offers more for less – more comfort, colours, and style – made using fewer components.

Move with the kinematic monoshell

Setting out to animate a shell chair, the designers at Studio 7.5 used 3D printing to iterate through prototypes of the monoshell until they achieved something rare in a side chair: a recline that feels natural in a chair that moves with you. The geometry of the design allows your body’s pivot points to create the right counterbalance for a proper ergonomic sit – an experience that leaves you feeling supported and energised as you move in the chair, and about your day.

Change it up with 3D Knit

The chair’s optional, removable and interchangeable 3D-knit seat pad easily slides directly into the shell, no tools required, and can be swapped out for one of the other 20 textile colour options if your space needs a refresh. Plus, it’s made from 50% post-consumer recycled content, and because it’s knitted to the chair’s exact dimensions, there’s zero fabric waste.

Find joy in colour

The playful colour palette for the Zeph Side Chair’s shell and base was designed to complement and enliven the home, office, college campus, or anywhere in between, allowing you to get creative in pairing the chair with your unique sense of style. Enjoy the return of dipped-in-colour, one hue from top to bottom, which debuted on Zeph predecessor, Cosm.

The story behind Zeph

Berlin-based Studio 7.5 found the initial inspiration for the Zeph Chair with the help of the students at the universities where they teach. Eventually, their iterative design process led to an entry-level chair that doesn’t compromise on comfort or style, and one that bridges the gap between Herman Miller’s iconic mid-century designs and the ergonomics of today’s work chairs.
