Memory foam toppers aren't without their disadvantages. However for most people they will give better support to the body and that can only be a good thing for people suffering from sleep issues. You'll find that they are an effective way to improve the quality of your sleep and that affects the quality of your life.
Another term used by Restonic is the '5-Zone Sleep System'. Again, springs are strategically aligned to provide the best support for areas like hips, neck and shoulders. Likewise other manufacturers make 'correctly aligned' springs.
Whether or not a machine can do a better job of choosing your mattress than your own judgment is debatable but maybe it can? After all, when choosing a mattress you're supposed to lie down on it for at least 15 minutes, try out your various sleep positions, and, ideally, lay down on it in your pajamas - or whatever else you sleep in. Doing this is not easy as most consumers feel very self conscious when lying down on a mattress in a busy department store.
There are basically three types of Sealy TrueFoam mattress to choose from; the 8 series, 9 series and 11 series - the number is the thickness of the mattress in inches. The 8 series comes with 5" of high-density foam in the core and 3" of memory foam in the top layer. The 9 series comes with 6" of high-density foam in the core and 3" of top layer. What exactly are the benefits of the 9 series over the 8 series I can't really say as both have a 3.5" top layer of memory foam - I don't see how an extra one inch of high-density foam in the core makes the 9 series any better than the 8 series. The 11 series comes with 6" of high-density foam in the core, a 3.5" visco middle layer and 1.5" convoluted visco top layer.
