We'll cross that bridge when we come to it, and fwiw, this is a pretty firm foam -- we didn't want anything too plush or "sink"y. There is no way we could have stored it without paying to do so, in which case, it'd be cheaper to get a new mattress in the future, anyway. :)

(Oh, and if you missed the update in the DSLJ post, it was taken, so I'm glad it will have more life.)
