PostureFit Replacement Kit for Herman Miller Aeron Classic Chairs by OfficeLogixShop

This product is designed and manufactured by OfficeLogixShop. It is not an OEM Herman Miller part. “Herman Miller” and “Aeron” are referenced solely to identify the compatible chair model. OfficeLogixShop is not affiliated with or endorsed by MillerKnoll, Inc.

Restore the advanced ergonomic function of your chair with the PostureFit Replacement Kit for Herman Miller Aeron Chairs. Unlike the standard lumbar pad that supports the lower back curve, the PostureFit system supports the base of your spine (the sacrum) to maintain a healthy pelvic tilt. This OfficeLogixShop kit provides everything you need to upgrade or repair the support system on your Aeron Classic Size B or C.

Sacral Support: The ultimate ergonomic upgrade to keep you sitting upright and fatigue-free!

Why Upgrade to PostureFit?

If you find yourself slouching or feeling fatigue in your lower back, the standard lumbar pad might not be enough. The PostureFit system fills the void between your pelvis and the chair, encouraging a naturally upright posture without effort. It is the preferred choice for users who spend long hours seated.

Product Highlights

Stop Slouching

By supporting the base of your spine, it helps your pelvis tilt forward naturally, maintaining a healthy posture during long hours at the desk.

Prevent Fatigue

More than just a replacement part, it is a complete upgrade for your back health. It prevents the "C-shape" slump that occurs during long sitting sessions.

No Drilling Required

You do not need to drill holes in your chair. The cable simply passes through a small opening in the bottom center mesh weave without damaging the material.

Size B and C Only

This OfficeLogixShop kit is designed exclusively for Size B (Medium) and Size C (Large) Aeron Classic chairs. It will not fit Size A frames.

Frequently Asked Questions

Do I need to drill holes to install this kit?

No drilling is required. You only need to pass the cable through a small opening in the mesh weave. This is a standard step and does not damage the chair.

Which side does the adjustment knob go on?

Install the knob on the right side of the chair (the same side as the height adjustment lever) to ensure proper cable routing.

How do I align the knob for installation?

Turn the knob until it forms a triangle shape with 1 point facing upward. This creates enough clearance to insert and tighten the mounting screw.

Is this compatible with Size A chairs?

No. This kit is designed for Size B (Medium) and Size C (Large) Aeron Classic chairs only.
