Seat foam to fit Herman Miller Mirra 1 

Moulded (not roughly cut) to specifically to replace the foam for the Mirra 1 chair with the flexifront adjustable handle under the thigh area of the chair it will not fit chair with the fixed seat front. 

Foam is for the  Mirra 1 chair. The Mirra 2 chair does not have a seat insert so if your chair has one it’s Mirra 1

To fit the foam you will need to remove the seat from your chair. To so this undo the bolts either side of seat, slide the seat off, remove the old insert, and slide in the new one. We will supply a video to assist.
