EPS Foam detached?

[Unregistered]

I have a Keyfit 30 that was purchased in 2007. Today when I went to put the cover back on I realized that the entire piece of foam had come unglued from the seat.
When I called Chicco they told me it was a "safety concern" (only after confirming that the seat was no longer under warantee).
But the more I think about it the more I wonder - how are 2 splotches of glue supposed to hold the foam on? Why is their glue better than if I just tape it on? Why do some manufactuers sell replacement foam if this is truly a safety concern? And why do I own another seat that never had EPS foam and that is NOT a problem?
Obviously, I will not do anything against their recommendation, my child's safety is more important, but I do wonder if they are not just trying to get me to buy a replacement (the customer service rep said that would be the probable outcome).

Mine was just taped in with brown paper packing tape... http://picasaweb.google.com/joolstag/LeahInCarseats#4982070571643306002

Probably that's just the best answer they can offer you over the phone without seeing your seat, but many other companies have allowed/recommended just taping foam back in place as long as it's not chipped and crumbled to the point of uselessness (it should be an even thickness and not crumbled around the head for good protection in a crash).

There's absolutely nothing wrong with the foam, not even a pellet of the stuff is missing. I guess that's why I found it so disturbing when she told me I'd need to replace it - it doesn't expire until 2013!!
