What is Posturefit?

When you are sitting on an Aeron chair, and you feel that there is a lack of proper support to the base of your spine, you can install the Posturefit support system on the chair.

A Posturefit ensures that your spine maintains its S-shape and that you do not develop fatigue or a compromised posture due to back issues.

Posturefit is made up of two pads that are entirely independent of each other. The top pad is to exert pressure and provide support to the lumbar region of the back, while the lower cushion is for sacrum support or to support the base of the spine.

One of the most significant drawbacks of Posturefit is they have only been constructed for the original, old version of the Aeron chairs. As of right now, there is no version of the Posturefit that can fit the newer Aeron chairs.
