Foam is a good insulator - not likely what you want.
That's what I was thinking, and it makes perfect sense to me, but it seems they have technology in some of these mattresses that address this to a point where it's superior to what you can get with a traditional mattress. Including this gel stuff that's supposed to be coming out soon.
I also spent about 15 minutes sitting on one (not the new ones with the gel) in the store in one place, trying to mimic what I felt when reading in bed. It didn't get warm at all, but again, that's when I was fully clothed, had no sheets or anything on top of me, and in a giant, cool, storeroom.
Don't be afraid to spend - inexpensive mattresses break down faster.
I don't think that'll be a problem. We might be getting help there as an anniversary gift

Also go firmer than you might think you want. Mattresses never get firmer with age, just the opposite.
Don't worry, I'm all for the firmer mattresses. I really do not like the soft ones in the hotels I've been to.
You shouldn't feel the bones of the mattress, if you feel them now...
That's another problem, I don't know what I feel. The saleswoman asked me questions about how it felt, and I don't know if I'm crazy or what but it's hard for me to know how to describe this stuff, or tell the difference, especially without spending a night on it. I know by the results, and if I have a good night's sleep on it, I know I like it. But that's hard to do here.
Best mattress I ever slept on (going on 7 years now) is Tempurpedic.
See, that's why this is hard. It's a subjective thing but it seems like something I can't know in advance of buying one, and if I'm wrong then I'm either out a few hundred dollars to return it or I'm stuck with it for a couple decades

As for staying cool... fewer blankets?
HA! Yeah, that's not possible. I already sleep most nights with only a bedsheet. Some nights without even that. Like I said, I run hot
