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. The Aeron PostureFit Support Kit is recommended for people who sit up straight in their chair to perform tasks. It is compatible with all sizes (A, B, or C) of Aeron Chair and Aeron Stools, provided the chair has a Tilt Limiter option. To identify whether your 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, stand behind the chair and feel for the raised dots under the top edge of the back frame. One dot is Small size, two dots in a row is Medium size, three dots in a triangle is Large size.
