I still don't have a new driveway -- apparently there were some delays, and the most recent word I heard was that maybe they'll be here Monday or Tuesday -- but I do have a new mattress.
And, man, mattress shopping got weird since the last time I had to think about it. (Not that I thought about it very much, then. It was basically: I need a bed, this affordable bed frame/mattress/box spring/headboard combination at the local furniture store seems fine, end of shopping.) It used to be a mattress was a big rectangle full of springs, and all you had to do was pick one that seemed to have the right firmness, but while I wasn't paying much attention there was, like, this bewildering explosion in mattress technology.
Anyway. I got a traditional spring one with a cushiony pillow top on it. Which, after sleeping on it for a couple of nights, I am thinking may not have been the ideal choice. The top is foam, and while I'd heard foam beds retain a lot of heat, I figured one layer of it, which supposedly also features some kind of gel to help keep it cool, would be okay. I can definitely feel the difference in how warm it is, though. It'll be great for winter, but is less than ideal in July, when we haven't had a day that hasn't hit triple digits in over a week. Still, if I replace my comforter with a lighter blanket, I think I'll be fine. (I can't sleep without some kind of a blanket. I feel too exposed, or something.) It's also waaaaaay thicker than my old mattress, which is going to take some getting used to, if only because it means I have to adjust my aim when groping for my glasses on the headboard shelf in the morning.
Unfortunately, I'm also not sure it's helping with the fact that my back often tends to feel a bit stiff or achy when I wake up, which was kind of the point of the exercise. (Although, honestly, the old one did need to be replaced, regardless. It was 15 years old, and becoming noticeably concave.) Likely said stiffness has more to do with my poor posture during the day than it does with my sleeping position. (The ergonomics at work aren't bad, but I have noticed I tend to slump a lot when sitting in front of the computer at home. And I do a lot of sitting in front of the computer at home.) I'm also a little worried, though, that in my paranoia about ending up with a mattress that's too firm -- hard mattresses being the source of some unbelievably miserable nights I've spend on hotel beds -- I might have ended up with one that's just a little too soft. Sigh. How on Earth can the human body possibly be so sensitive to such things? Didn't we evolve to sleep on beds of leaves or something?
