Replacement Seat for Herman Miller Mirra 1 Chairs, Flex Front, Refurbished
If the mesh on your Mirra seat has sagged or torn, or the seat pan has worn out, this is the fix that keeps the chair. A genuine Herman Miller Mirra 1 Flex Front seat, fully and professionally refurbished by OfficeLogixShop and inspected, in the standard graphite finish that matches the Mirra's graphite frame. You move your existing Flex Front mechanism across to it and your Mirra sits like it should again, so professionals and gamers can extend the life of a Mirra 1 without buying a new chair.

| Condition | Genuine Herman Miller part, refurbished and inspected for reliable daily use |
|---|---|
| Seat mesh | Suspension mesh that moves with you, contoured to keep your hips and thighs aligned, open so air flows through and you stay cool |

Don't start with a power drill. Break the tension on each bolt by hand with a T40 tool first. Starting with a drill is the leading cause of stripped hardware on this job.
How the Mirra seat replacement works
- Loosen the bolts by hand with the T40 tool and remove the old seat.
- Unbolt the Flex Front mechanism from the old seat.
- Fit the mechanism to the renewed seat with the provided screws.
- Mount the seat back on the chair.
The installation video further down and our written Mirra seat replacement tutorial show every step. To check for Flex Front, look for a front seat edge that adjusts for depth (on a Fixed Front seat it never moves). If yours does not move and you are unsure which version you have, send us a photo before ordering.
Replacing the Mirra 1 Flex Front seat
Whole seat, seat foam or the Flex Front bracket? And is it a Mirra 1?
A tired Mirra seat has three usual causes, and this seat only fits one generation. Check both before you order.
Sagging or torn seat mesh, or a worn-out seat pan
This complete seat is the fix.
You find black crumbs under the chair and feel the hard frame
That is the foam cushion under the mesh crumbling. Our Mirra 1 seat foam replaces just that, in minutes.
The front edge no longer adjusts or feels loose
The part that links the Flex Front seat to the chair's mechanism may have broken. See the Flex Front seat bracket.
Mirra 1 or Mirra 2?
This seat is for the Mirra 1 only. The Mirra 2 took over from the original Mirra in 2013, so any Mirra built before then is a Mirra 1; the date label under the seat tells you when yours was made. If you are still unsure, send us a photo and we will check for you.
The Mirra 1 Flex Front seat, seen up close
If you are looking for a Herman Miller Mirra seat pan or seat mesh replacement, this complete seat brings both in one piece.
Mirra 1 seat replacement: your questions
What specific tools do I need for installation?
A T40 long-handle driver or a star key wrench. Loosen the bolts by hand first to avoid stripping them.
How do I replace the mechanism?
Unbolt the Flex Front mechanism from your old seat and install it on the renewed seat with the provided screws.
Is this compatible with the Fixed Front Mirra?
No. This replacement fits only the Flex Front version of the Mirra 1. Please check your model before ordering.
Can I use a power drill to remove the seat?
We strongly advise against starting with a power drill; it is the leading cause of stripped hardware. Always break the tension by hand first.
Will it fit a Mirra 2?
No. It is made for the Mirra 1 only. The Mirra 1 or Mirra 2 guide above shows how to tell them apart.
Do you offer bulk pricing for a fleet of Mirra chairs?
Yes. OfficeLogixShop has clients across the USA, Canada, the UK and dozens of other countries, and offers bulk discounts to companies that refurbish their Mirra chairs instead of replacing them. Contact us for bulk pricing and international shipping options.
