Herman Miller, a part of the MillerKnoll collective and a global leader in innovative design and furnishing solutions, announces the return of the renowned collaboration that enthralled the design world with the Cosm, Mirra, and Setu chairs. Studio 7.5 and Herman Miller have paired up once more to reveal the Zeph Chair, their latest collaboration.

As people across the globe continue to settle into new ways of working, many will continue to need products in both homes and office environments that are as aesthetically pleasing as they are purposeful.

“Zeph marks the introduction of a chair tailored to our new ways of working. It’s an elegant, customisable, and colourful addition to Herman Miller’s market-leading portfolio of high-performance seating.” says Ben Watson, President, Herman Miller.

Zeph aims to bridge the gap between Herman Miller’s iconic mid-century designs and the ergonomics of today’s office chairs. The result is an accessible design that doesn’t compromise comfort or style.

With its slim profile and an easy-to-adjust design, users will find Zeph a colourful companion capable of supporting a variety of needs while seamlessly incorporating itself into the scenery of any room. Its versatility easily translates into traditional office settings, providing architects, designers, and consumers a refreshing and flexible choice.

The Design

Zeph’s clean and uninterrupted silhouette is intentional. However, customers shouldn’t be deceived by its simple, organic appearance. Under the seat lies hidden technology designed to deliver a seamless ergonomic experience that leverages human-centred motion. This allows Zeph to create a natural, fluid motion that works for all body types.

“Our ambition was to create an animated shell chair. What first sounds like a contradiction became possible by utilising the inherent materiality of plastic: being flexible and capable of providing a spring- loaded mechanism. Zeph’s joyful aesthetics provides surprising ergonomic benefits too.” said Burkhard Schmitz, who helms Studio 7.5 with Carola Zwick and her brother Roland Zwick.

After many iterations of 3-D printed prototypes, Studio 7.5 perfected a one-piece seat and back that actually moves with the person sitting in it. While most chairs are static, the kinematic plastic mono shell on Zeph offers a natural recline that uses the sitter’s pivot points to create the right counterbalance and change posture seamlessly.

The expansive colour palette also took inspiration from the past. “One of the things we wanted to pick up from Herman Miller’s mid-century era was the optimistic and delightful idea of the future. We wanted Zeph to be playful and happy.” adds Zwick. The palette or “the crayon box,” as Studio 7.5 says, is intended to be inviting for a variety of tastes, and to let users have some fun.

The uniform hue design, achieved by pioneering dipped-in colour options, was first introduced to Herman Miller by Studio 7.5 through the launch of the Cosm chair. Through this process, colour is applied purposefully to the entire chair, all the way down to the casters, accentuating the sculptural beauty of its form.

3-D Knit Technology

In addition to the bright, dipped-in colour options available for the chair, every Zeph shell can be further customised through the addition of upholstery, either as a seat pad or a unibody (which covers the entire front of the shell).

The unique construction of this upholstery is a first for Herman Miller. The upholstery can easily be mounted and replaced without tools for easy cleaning or to swap different colours, and it utilises revolutionary 3-D knit technology, with each seat option made of 50% recycled polyester yarn — offering sophisticated colour choices and cushioned comfort.

“As professionals enter a new era of empowerment and flexibility, Herman Miller is responding in kind with Zeph — a design that can continue to be customised even after it’s left our care.” adds Watson. “Between colours, shell choices and texture options, Zeph is a thoughtfully designed solution fit for any life or space.”


 Zeph is available in eight distinct colours with 20 seat pad upholstery options. The unibody upholstery options will be available later this year. A side chair version of Zeph with the same kinematic mono shell, will also be introduced early next year. Zeph is now available for contract clients at specific business pricing via an authorised Herman Miller or MillerKnoll dealers. Zeph will also be available to purchase through Herman Miller’s retail locations across the globe in August.
