Restore the premium comfort of your Herman Miller Aeron Size C with our specialized Seat Foam Insert. The original foam pad is crucial for cushioning the front edge of the seat frame, but it degrades over time. This high-density replacement is contoured specifically for the wider seat pan of the Size C Aeron, eliminating thigh pressure and bringing back that "like-new" seating experience.
Comfort Restoration: A simple, tool-free upgrade designed exclusively for the wider seat of the Aeron Size C!
Why Replace Your Seat Foam?
If you feel the hard plastic frame pressing into the back of your legs, your foam insert has likely flattened or disintegrated. This is especially common in older chairs. Our OfficeLogixShop foam insert provides a fresh layer of supportive cushioning, ensuring circulation isn't cut off during long work sessions.
