Herman Miller
Since the Eames Screen is still being made, you should be able to get replacement parts from any reputable Herman Miller dealer.
I suggest contacting:
retromodern (retromodern.com)
hive (hivemodern.com)
highbrow (highbrowfurniture.com)
I bought my real, honest-to-god Betroia seat pads in Canary yellow from Highbrow after stupidly buying some horribly ugly knockoffs.
