Actually, with some of the advances in foam materials, my impression is that foam mattresses are actually a blast from the present, and possibly the future. Even most spring mattresses have a significant foam comfort layer above the springs now, and the advantages of having springs below vs. latex and some of the other higher quality foams are becoming increasingly questionable -- especially if they're not really high-end springs.
