Studio 7.5
The designers of Berlin-based Studio 7.5 share an attention to the smallest of details, or what they call EMC – every molecule counts. “If you ask specifically for what terms we use,” explained partner Claudia Plikat prior to her death in 2013, “there is one German word: It’s called einfach – simple, but not too simple.” It’s the concept of being on a mission to boil things down to their essence.

Frequently Asked Questions
All configurations of the Cosm Chair weigh 35 pounds.
Herman Miller manufactures the Cosm Chair in the United States, and we operate production facilities in Michigan where the chair is assembled.
The Cosm Chair supports users up to 350 pounds.
The Cosm Chair's seat height ranges from 14.875 inches at its lowest position to 21 inches at full extension across all three back height options. This 6.125-inch adjustment range accommodates users from approximately 5 feet to 6 feet 4 inches tall when paired with standard desk heights.
The Cosm requires minimal adjustment compared to traditional ergonomic chairs. The primary control is the seat height lever located beneath the right side of the seat. Pull the lever upward while seated to lower the chair, or pull it while lifting your weight to raise the seat.
The Auto-Harmonic Tilt operates automatically without user adjustment. When you recline, the mechanism responds to your body weight and movement intensity. There are no tension knobs to turn or tilt locks to engage. The flexible frame adapts continuously as you shift your posture throughout the workday.
For chairs equipped with adjustable arms, press the lever on the outer arm post to unlock vertical movement. Raise or lower the arm to your preferred height, then release the lever to lock it in position.
The Cosm Chair measures 26.75 inches deep from front to back across all three size options. The fixed seat depth is 15.5 inches from the front edge to the backrest.
Studio 7.5 created the Cosm Chair for Herman Miller. Founded in Berlin in 1992, Studio 7.5 has established a reputation for performance seating innovation, having previously designed Herman Miller's Mirra Chair series. Their approach to the Cosm focused on eliminating adjustment complexity while maintaining ergonomic integrity.
Herman Miller backs the Cosm with a 12-year warranty covering materials and workmanship under normal use conditions.
