I've never paid a whole hell of a lot of attention to mattresses. I'm made of pretty sturdy stuff and can sleep on a hardwood floor just as easily as I can on one of those hifalutin sleep number beds -- in fact, much better -- those things SUCK!
Lately, though, I've perused a bit more sleep aid literature on account of having a girlfriend with a bum shoulder and a back that gets all clenchy-like after catching zzz's on our somewhat saggy mattress (dramatization of sleepless night in image above).
Awhile back, we stopped in at a Healthy Back store and flopped around on some of the Temper-Pedic beds. They cost a King's ransom, but I have to admit they're pretty damned nice.
Recently, I've been noticing their ads everywhere and it dawned on me that I should write a coverage...so this is one of those "real world observation" types that seem to work out for me more often than not.
Moderate ambition, full confidence...sleep easy!
