Just spent 3 nights sleeping on one in a hotel and it confirmed my tester impressions when mattress shopping that it would lead to a bad nights sleep. I'm sure there are maybe some wonderful to sleep on foam mattresses but they all seem spongy and hot to me and those are the last things I want in a mattress.
Keep in mind that memory foam and latex foam are very different from each other. Since I sleep "hot" I don't like memory foam at all, but Talalay latex suits me fine.
