Our Herman Miller Cosm chair review

For the designers at Berlin based Studio 7.5, the latest Herman Miller chair, the Cosm, features for what has become for them a new holy grail, and a benchmark for personalised and automated comfort. Cosm’s new Auto-Harmonic tilt is the successful outcome to a long design journey.

Herman Miller COSM chair review

The gifted designers knew, even when working on the precursors to the Cosm, such as the Mirra 2, that the ideal chair should provide a natural counterpoint to the person sitting in the chair and should work intuitively with them rather than fighting them and forcing them to make their own adjustment decisions. 

“You should have a chair that allows you to change postures as easily as possible,” Roland, a designer at Studio 7.5 declared. “You can only do that with a chair that is correctly adjusted, so we wanted to build a chair that does that part for you.”

Studio 7.5 use the following analogy to describe their new Auto-Harmonic tilt feature.

“A tilt is to a chair what a transmission is to a car, and like transmissions, some are manual, and others, such as Cosm’s, are automatic.”

With other self-adjusting models, the chair decides how you should sit by forcing you to adjust to the chair, Cosm, does not do this, it fits around you and adjusts itself to suit your sitting posture, thereby providing you with a smoothly balanced recline and personalised comfort.

Studio 7.5 and Herman Miller achieved this by inventing a complex, finely tuned mechanism that responds to the sitter’s vertical force and uses this force to power the tilt mechanism and move the fulcrum or balancing point, along a leaf spring to automatically adjust the chair’s tension.

The tilt alone doesn’t make Cosm the designers’ most refined design to date. It has taken a meticulous process of prototyping hundreds of hand-sculpted and 3D-printed parts to find the hidden path toward a seating experience unlike any other.

“One of the biggest challenge, or I should say, one of the biggest opportunities, was to determine how to attach the suspension in a way that made it blend into the frame as seamlessly as possible,” Burkhard says.

The answer came in the form of small “teeth” that allow the suspension material to clip into the chair’s frame while staying taut for even pressure distribution. The ingenious way that Studio 7.5 has attached the suspension to the frame is a prime example of what they call “industrial craftsmanship”, a guiding light in their design process.

“We like a product that is readable so that you can understand, even if you’re not a mechanic or an engineer, how you’re being supported,” Carola from Studio 7.5 explains.

‘Cosm is total comfort and style wrapped up as one entity’

The chair’s ergonomic design is further enhanced by Cosm’s Leaf Arm. These are the first of their kind.

“The elbow is a very delicate part of our anatomy; it wants to be placed in a very soft but firm spot,” Burkard explains. “Cosm’s Leaf Arms follow the overall functional and aesthetic intent of the chair by providing a simple and super slim visual appearance with superior comfort.”

Aware of how we work today, Studio 7.5 designed the arm to provide comfort for variety of applications. The Leaf Arms make holding a phone or book natural and comfortable, and the angle of the arms mean they don’t get in the way of a desk when it’s time to get back online.

Although technical and engineering challenges occupied much of Cosm’s development time, Studio 7.5 was no less dedicated to its aesthetic appearance.

With its continuous suspension and sculptural form, the chair appears as a single unified object, and not a collection of parts and pieces. This sense of unity is also reflected in its material composure.

“The monochrome coloring dematerializes the object,” Burkhard says of the dipped-in-color concept, in which they present the chair in one hue from top to bottom. “The chair is made out of many different metals and plastics, but ultimately, it’s just one thing.”

Our Verdict

The Herman Miller Cosm is a stunningly beautiful chair that has been designed from the ground up to support you, and save you time and effort by adjusting to how you sit, rather than you having to spend half your day trying to get it just right.

We can see why Herman Miller has chosen to create a different line with this product rather than launch it as an Aeron MKIII and cannibalise the Aeron sales, but in reality, the Aeron broke the accepted rules when it came to designing an ergonomic chair for prolonged use, and for us the Cosm takes this one step further and should be considered a worthy alternative or progression to the Aeron.
