Frequently Asked Questions

Who is the Herman Miller Aeron Size C designed for?

The Aeron Size C is engineered for taller, broader individuals—typically users between 5'10" and 6'6" in height and weighing up to 159 kg. The wider seat pan and taller backrest ensure proper weight distribution without constricting the thighs.

What colour is the Herman Miller Jasper finish?

Jasper is a sophisticated, warm neutral tone within Herman Miller’s remastered colour palette. It blends deep slate and warm grey undertones, offering a softer aesthetic than standard Graphite while maintaining a professional appearance.

What is the difference between Aeron Size B and Size C?

Size B is the medium option designed for average body types (5'3" to 6'0"), whereas Size C is the large model featuring a wider seat pan (510 mm vs 460 mm), higher backrest, and higher weight capacity to comfortably accommodate larger body profiles.

How does the PostureFit SL system work on the Aeron Size C?

PostureFit SL features two individual pads that flex independently to support both the sacrum (base of the spine) and the lumbar region. This stabilises the pelvis in a natural forward tilt, preventing slouching during extended sitting.
