How to Change the Flex Front Seat Mechanism on Your Herman Miller Mirra 1 Chair?

Welcome to our comprehensive guide on replacing the Flex Front Seat of your Herman Miller Mirra 1. This tutorial focuses on a crucial aspect of the chair's comfort and functionality. Let's dive into the steps for changing the Flex Front Seat mechanism.

Tools Needed:

  • New Mirra 1 Seat (Flex Front)
  • T40 Drive Long Handle Pair Head or Star Key Wrench
  • Electric Drill (optional, with caution)

Steps to Change the Flex Front Seat Mechanism:

Removing the Seat:

  • Start by removing the bolts from both sides of the seat to free it. It's crucial to use the correct tools—a T40 drive long handle pair head or a star key wrench—to avoid stripping the bolts. The drive long handle pair head is generally easier to use.

Removing the Old Flex Front Mechanism:

  • Once the seat is free, proceed to remove the old flex front seat mechanism from your damaged seat. Unbolt the screws as demonstrated to detach the mechanism.

Installing the New Flex Front Mechanism:

  • Prepare the new Mirra flex seat for the installation of the flex front mechanism. It's important to note that Mirra 1 seats come with two types of front mechanisms: flex front and fixed front. Ensure the replacement mechanism is compatible with your seat type before proceeding.
  • Install the flex front mechanism into the new seat, securing it in place with the provided screws.

Reassembling the Seat:

  • Slide the seat back onto its rails, ensuring it aligns correctly.
  • Tighten the bolts on both sides to secure the seat in place.

Testing the Mechanism:

  • After reassembly, test the functionality of the flex front mechanism and make any necessary adjustments to ensure optimal comfort and support.
