Herman Miller Aeron Classic PostureFit Kit Assembly Guide

Welcome to this PostureFit installation guide for the Herman Miller Aeron Classic chair. This tutorial walks you through each step to complete the setup.

1. Remove and Separate the Clip

• Remove the small screw at the bottom of the clip.
• Once the screw is out, take the clip apart as shown.

2. Orient the Chair

• Identify the side with the height adjustment lever and the tension control.
• Face this side to install the PostureFit correctly.

3. Position and Snap the Clip with the Knob

• With the PostureFit knob facing you, place the other piece of the clip behind the frame.
• Snap the part with the knob into place.

4. Create Space for the Screw

• Turn the knob until it forms a triangle shape with one point facing upward.
• This creates enough space to insert and tighten the screw securely.

5. Extend and Route the Cable

• Turn the knob to extend the cable to its maximum length.
• At the bottom center of the back mesh, create a small opening and slide the cable through.

6. Center and Hook the Bracket

• Check that the bracket is centered on the frame and sitting straight.
• Push it upward until it hooks securely.

7. Attach the PostureFit Pad

• Attach the PostureFit pad to the Y bracket.
• Make sure the wider part of the pad is at the bottom.
• Line up the holes in the bracket and the pad so they are ready for the bolts.

8. Insert and Tighten the Bolts

• Separate the bolts.
• Insert one bolt through the side.
• While holding it in place, insert the other and tighten both with a screwdriver.

9. Seat the Cable Tip

• With the cable fully extended, insert the tip of the cable into the larger opening and slide it down as shown.

10. Slide the Bracket onto the Rails

• Slide the bracket onto its rails on the back of the chair.
• Your PostureFit kit is now installed.
