Classic Aeron PostureFit Support Kit

Herman Miller’s patented PostureFit provides back support at the base of your spine, or sacral region, helping your pelvis maintain a natural forward tilt to prevent slouching. By doing so, PostureFit keeps your spine in healthy alignment to help eliminate lower back pain. Recommended for people who sit up straight in their chair to perform tasks, this kit is compatible with all sizes (A, B, or C) of the classic Aeron Chair and Stool, provided the chair or stool has a Tilt Limiter option.

To identify whether your classic Aeron has a Tilt Limiter, reach down with your left hand while sitting in the chair. If you locate one or two levers attached to the chair’s tilt mechanism, your Aeron has a Tilt Limiter.  

To find the size of an Aeron chair or stool, stand behind the chair and feel for the raised dots under the top edge of the back frame. One dot is the A (small size), two dots in a row is the B (medium size), and three dots in a triangle is the C (large) size.
