Achieving “an outstanding design”

The Celle chair began in the imagination of designer Jerome Caruso. Caruso was the first designer employed by refrigerator manufacturer Sub-Zero, has been their principal designer for more than two decades and is responsible for the company’s entire range of refrigeration units. But the Celle chair, he smiles, was the “Mt. Everest of fun. At the beginning, I imagined a highly engineered, ‘intelligent’ surface that could be the ultimate in seating comfort.”

From an ergonomics standpoint, Celle follows the lead of our Aeron and Mirra work chairs, with five ergonomics issues integral to the design of all three:

  • Size and fit. Anthropometric data from CAESAR (Civilian American and European Surface Anthropometry Resource) and other sources was used to ensure that the chair fits many different body shapes and sizes.
  • Pelvic stabilisation. The Celle backrest has our integrated, passive PostureFit contour.
  • Kinematics. Our proven Harmonic tilt mechanism was applied to Celle.
  • Pressure distribution. Throughout Celle’s development process, we used our pressure-mapping capabilities to inform the design of the cellular size, flex regions and contouring.
  • Thermal comfort. Special temperature sensors, called thermocouples, were used to evaluate upholstery options and inform textile selection.

“The bigger the challenge, the more fun it is to work out the solution.”
