As a former mattress salesman, I can confidently say that there is not, nor ever has been anything that compares to Stearns & Foster when it comes to quality, durability and comfort. They have a lifetime warranty on them, they never dip, sag, or breakdown etc in any noticeable way.
We used to pull people's used beds out of their houses when we would deliver their new beds (sold most brands), and you could see how the other brands held up after years of use. You can really see how good a bed is when you're pulling it out of a home after 15 years of use. In the 2 years I worked there selling and delivering, we never took a Stearns & Foster away - they would always have us put them in a guest room or take them to their kids house or whatever. Other brands would be tossed about 90% of the time. If you've got an extra $3k-$4k to spend on your next bed, do yourself a favor and get one of their high end models.
