This OEM replacement seat foam is designed specifically for Herman Miller Classic Aeron chairs in Medium B and Small A sizes. Made from medium-firm, durable foam with a carbon black finish, it restores ergonomic support and comfort. Easy to install with strong adhesive backing, it revitalizes your chair’s seating experience while maintaining its iconic look.

## Description

Replacement seat foam for carbon colored Classic Aeron chair, fits sizes Small A and medium B only. This replacement seat foam pad is attached underneath the front edge of the chair seat, where your knees would naturally fall. It can easily be adhered with strong double sided tape.

Review: OEM replacement - Fit well and and was installed easily by only letting the sticker backing only hanging off a little, and fully seating the insert before pulling the adhesive backing off. Wish it was a little more firm but seems to be an exact oem replacement.
Review: Thick, Durable, Great Fit for Pad Replacement - The original seat pad was ‘toast’. The replacement pad breaths life into my Aeron chair for many more years of service!
