Intercept Suspension: Breathable and temperature-neutral, the continuous form of this elastomeric suspension eliminates the gap between the seat and back, conforming to each person’s body to provide dynamic spinal support. Mix and match any of the six colors on the suspension and frame.
Flexible Frame:The thin but strong frame feels nearly non-existent and offers support while flexing so you can comfortably move your upper body.
Auto-Harmonic Tilt: Self adjusting mechanism that instantly and automatically provides balanced support and movement depending on the person’s body, posture, and the way that they’re sitting. This finely tuned comfort lets people move around as much as they want and comes without the need to twist and turn knobs. The only lever on the chair adjusts the height, so you can sit down, get to work, and forget about gravity.
Back Options: Cosm is offered in three different back options:
- Low-Back: The low-back, with its wrap-top, facilitates casual movement and lets people comfortably sit sideways with their arm draped over the top of the backrest.
- Mid-Back: The mid-back provides scapular support and easily adapts to any setting, from workstations to project rooms to conference areas.
- High-Back: The high-back fits like a glove while providing upper-thoracic support and a sense of comfort and privacy.
- No Arms: Allows the chair to fit easily under a desk or table, and supports a variety of activities that require freedom of movement.
- Fixed Arms: Arms are set at 8.6 inches above the seat and cannot be adjusted. Ideal for short-term-use areas like conference rooms, multi-guest workspaces, and more.
- Height Adjustable Arms: Height Adjustable Arms adjust 4.4 inches vertically from 7 inches to 11.4 inches above the seat. This gives you the ability to support your arms at a comfortable height without straining your shoulders.
- Leaf Arms: Aiming to reinvent the task chair arm, Studio 7.5 developed Cosm’s Leaf Arms, which provide a large, comfortable resting place for your elbow. The soft but firm cradle design stabilizes your body and allows you to place your elbow wherever it’s most comfortable, and the fixed design turns the arms into handles that make getting in and out of the seat easy.
- Casters for Carpet with Quiet Roll Technology: Designed for use on low- to medium-pile carpet, such as commercial or Berber, these 2.5 inch casters have durable black nylon wheels and includes Quiet Roll Technology reduces noise on hard surfaces.
- Casters for Hard Floors or Carpet with Quiet Roll Technology: A versatile caster that can be used on hard surfaces, such as wood, ceramic tile, vinyl tile, or carpeted floors, this 2.5 inch caster is made of durable black nylon, with a soft tread that gives the chair better traction and includes Quiet Roll Technology reduces noise on hard surfaces.
- Casters for Hard Floor or Carpet with Medium Roll-Resistance and Quiet Roll Technology: A versatile caster that can be used on hard surfaces such as wood, ceramic tile, vinyl tile, or carpeted floors. This 2.5 inch caster features medium roll-resistance that prevents the chairs from rolling away when they are not occupied. Casters are made of durable black nylon, with a soft tread that gives the chair better traction and includes Quiet Roll Technology reduces noise on hard surfaces.
- Glides for Hard Floor or Carpet: Universal glides that can be used on hard surfaces such as wood, ceramic tile, vinyl tile, or carpeted floors. The glide is 2.5 inches in height and made of durable black nylon with a soft polyurethane bottom surface. This option is ideal for customers looking to swivel and adjust the seat height while remaining in one location.

PRODUCT DESIGN STORY
For the Berlin-based designers at Studio 7.5—Carola Zwick, Roland Zwick, and Burkhard Schmitz—their latest chair for Herman Miller represents something of a holy grail: a design that creates a new reference point for instant, personalized comfort. Cosm’s new Auto-Harmonic Tilt, in particular, has been a goal they’ve worked toward for years.
The designers knew, even when working on predecessors like Mirra, Setu, and Mirra 2, that the ideal chair would provide a smooth feeling of natural balance. “You should have a chair that allows you to change postures as easily as possible,” Roland says. “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.”
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 the body to conform to the tilt’s movement. Cosm’s Auto-Harmonic Tilt puts the person first and responds to them—no matter their posture—providing a balanced recline and personalized comfort. Studio 7.5 and Herman Miller perfected the self-adjusting tilt by inventing a complex, finely tuned mechanism. Accounting for the sitter’s vertical force—which is always in flux—the gears within the tilt move the fulcrum 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; a meticulous process of prototyping hundreds of hand-sculpted and 3D-printed parts paved the path toward a seating experience unlike any other. “One of the biggest challenges—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 says.
The chair’s ergonomic design is further enhanced by Cosm’s Leaf Arms—the first of their kind. The design began as an ungainly piece of foam wrapped over wood, but over time, it’s shifted shape, size, and nicknames—including motorcycle seat, half-pipe for your arms, and Dumbo ears. “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.” Cognizant 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.”
The German word for design is entwerfen, which roughly translates as “to throw.” According to Carola, that’s “throw something a little bit ahead of the curve, or ahead of what you know, to help pull you in the right direction.” With Cosm, “throwing” led Studio 7.5 and Herman Miller to their most sophisticated design yet.
Burkhard Schmitz and Carola Zwick started their studio as a team of six in Berlin in 1992. The group was looking for the freedom to work on projects that interested them, and for the freedom to do so without bosses or titles.
This is the way they’ve operated ever since. “Everybody does everything,” says Schmitz, speaking for the group that now includes Carola’s brother, Roland Zwick, and a small team of seven. “That’s how we cultivate ideas and maintain our openness and curiosity.”
The group’s name—Studio 7.5—comes from an early idea to rent a 7.5-ton truck, put a model shop in it, and drive from one project site to another. Obviously, freedom of movement is important for these designers. They move freely—and smartly—when designing products for their clients.
The complexity of design problems, Studio 7.5 believes, requires collaboration, and repeated testing of ideas in full-scale models until the most elegant answer emerges. “You really have to work in three dimensions when designing products,” notes Roland. “Computer drawings just don’t give you the feel, the touch, the smell.”
They love designing furniture, or as they prefer to call it, “equipment,” as in the tools people need for the work that they do. They find designing office chairs in particular to be most rewarding and have worked with Herman Miller on the award-winning Setu, Mirra, and Mirra 2 chairs—and now, Cosm. “We define not only how the chair looks but how it performs,” Carola says. As to how Setu, Mirra, and Cosm all perform for you, they provide comfort no matter how or where you sit. “Our goal is to enable people to assume roles similar to that of a craftsman in his shop, surrounded by what he or she needs to be most productive.”
