Memory Foam is something developed by NASA which has since spread into the consumer markets. One of the most popular uses of memory foam is in bedding. If you push a hand into memory foam it will leave an impression of the hand which will then stay for a bit and slowly return to the flat, normal state. If you sleep on a pad of memory foam then it will leave an impression of your body in the surface. The advantages of memory foam are that it provides excellent support to the parts that need it most. In good quality toppers you will even find that the density rating (how long it takes for something to 'sink' into it) changes in the middle, giving more support to the torso which is heavier then the legs.

Like Sealy, Simmons didn't lead the way in development of viscoelastic, however they now manufacture their own version and even claim to have developed the 'next generation' of this type of mattress. It is true that the biggest complaint against memory foam has been a 'sinking feeling' - therefore not being able to move freely whilst lying down - and that it tends to 'cook the sleeper' because body heat is not dissipated quickly. Simmons claim to have solved both of these problems using their version of foam called NxG Advanced Memory Foam. From what I've garnered there does seem to be a small reduction with the quicksand feeling many customers complain about. With the claim as to heat reduction, I can't say one way or the other. The one overriding opinion is that the Simmons ComforPedic mattress is cheaper than a Tempur-Pedic mattress, though a little softer, and offers good value for money.
Personally, having tried out both a Sealy Posturepedic mattress and a Restonic I could not say one was more comfortable than the other. Also, having done some research about consumers who bought both, it was impossible to say which was better over the long term.
