Although there are many different thicknesses and densities, a memory foam mattress topper is designed to sit on top of an existing mattress to make it more comfortable.
The problem is that memory foam mattresses are, by design, not meant to be set onto a "soft" surface, they have to go onto a hard surface.
A platform bed that has a solid slab of wood is ideal to sit a memory foam mattress onto.
If it weren't for moisture and the inconvenience of getting in and out of bed, you could sit a memory foam mattress right onto the floor with excellent results.
When you buy a whole memory foam sleep system you get memory foam pillows, a memory foam mattress and a foundation (like a boxed spring, but without any springs).
Buying a topper and putting it onto a mattress, especially a worn out one, defeats the whole concept.
Memory foam provides it's unique comfort only when it does all the giving from the top down and is supported totally at the bottom.
If your mattress is worn out or if you sit the memory foam mattress topper onto a boxed spring, the topper is going to sink in everywhere the mattress or boxed spring sinks in, defeating the way it's designed to work.
For many people, any relief at all is better than nothing, so if you realize that a memory foam topper isn't meant to be a replacement for a memory foam sleep system, then let's go ahead with our focus on toppers and what benefits you can expect from them.
Memory foam mattress toppers, also called bed toppers, are made in varying thicknesses and densities.
(if you aren't familiar with the term density regarding foam products, you should check out my monthly video e-zine, "Gifts, Gadgets and Goodies" and you'll also receive the FREE report "The 5 Deadliest Sins That Most People Commit When Buying A Memory Foam Mattress...And How To Avoid Them!")
The most common memory foam toppers are 2" or so in thickness. There are a couple of really cheap ones that measure 1 1/2" thick. The best ones are 3" to 4" thick and of a denser material than the cheap ones.
If you have a choice, try to buy the 4.0 lb. to 4.5 lb. density toppers because they have the best support and will last many years.
NOTE inserted 9/14/2009: After 5 long years of searching, I've finally located a manufacturer that makes a product that meets my stringent standards.
I've put up a website to show you what a high quality, American made memory foam topper can be sold for at a fair profit. You might want to check it out just for kicks.
The low density toppers, of 2.5 lb. to 3.5 lb. will only continue to recover from your weight for about 10 to 12 months. After that, they will start to flatten out and show body impressions.
Remember never to place a mattress pad on top of your mattress topper because memory foam works off of your body temperature and anything you place between your body and the temperature sensitive foam will greatly diminish the way your topper feels.
Remember, any memory foam mattress topper you purchase will be better than no topper.
In some cases, you can spend less and get a great mattress topper that you'll be happy with for years to come.
The main thing, again, is to look for the density of the foam and the thickness of the topper that you'll be sleeping on for the future.
