Hi 22,
I'd recommend to look for something a little better. Tempsoma sounds like some kind of disease. Actually, what it does sound like is a hybrid-copy of the names of two major brands. Tempur Pedic, and I can't think of the other name at the moment... it'll come back to me.
Names aside, there's a number of reasons why I don't suspect it to be that great of a mattress. For one, visco elastic foam is available in different qualities, and the density rating only tells part of the story. The Tempsoma's top layer is 4 pound visco, which if I remember correctly, is on the low side for that type of foam, and is one potential quality indicator.
There's also been tons of hype over the years regarding "memory foam" mattresses, and a resulting market to fulfill demand based on that hype. Long story short, there have been lot's of medium to low quality copycats. But, even the best quality visco mattress has it's drawbacks, which brings us to the next point. Resiliency. Meaning, the foam's ability to "push back" against pressure. Whereas latex foams are generally "open cell", and the cells act like millions of little springs, visco is closed cell, and bottom out at a certain point much more easily. This effect is augmented by body heat, and the visco conforms to you. The two problems with that are, because the cells bottom out, the foam becomes harder at the points where they do, and secondly, if you change position, it takes a bit for the foam to rise back up, leaving a depression for a couple or few minutes. Depressions in the bed tend to try to suck you back into them like a black hole. Additionally, the lower quality visco's bottom out quicker than the better ones.
All in all, if you're looking for a very good quality foam mattress without breaking the bank, my recommendation would be to stick with high density latex foam. Take a look at Otis, and Gold Bond. A couple years back, I did way more research on this subject than neccessary, and became Mr. foam mattress expert. Found a few shops in NYC that had both brands and personally tried out every model to be found. Both makers are a cut above any of the copycats I found around Long Island. And don't be put off by the fact that they're primarily directed at the futon market. All the same technologies apply to modern, high quality futon matresses as do the box frame/foam models from huge name brands.
As for myself, I got the Otis Liberty. That model had the characteristics I liked best, but there are many to choose from. I didn't have tons of money to spend, but wanted something really good. Hence, all the excess research was all about trying to get the most bang for the buck, and I got it. I paid $350 for the mattress from a reputable internet dealer, and it's excellent. Lower quality items sell in brick and mortar stores for more than that, and are not as good.
A good mattress is part of a good night's sleep, and if you get the doctor recommended 8 hours a night (which I sure as hell don't), that's a lot of time in bed. It pays to know exactly what you're getting, regardless of price. Speaking of which, if you don't mind dropping a bigger chunk of change, reflex polymer mattresses are supposed to be pretty hot stuff.
Lots of good information at
Futon Life, and also
their forum. Happy hunting, and sweet dreams!... lol.
