## Description

Herman Miller’s patented PostureFit Kit 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 Classic 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 Classic Aeron Chair and Classic Aeron Stools, provided the chair 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 Classic Aeron has a Tilt Limiter. To find the size of an Classic 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. Care & Maintenance: For normal cleaning, wash plastic surfaces with a soft cloth soaked in mild detergent and warm water. Rinse thoroughly and dry with a soft cloth. Do not use solvents or abrasive kitchen cleaners.
