Memory Foam Mattress Topper   

Prior to going out and buying a memory foam mattress topper to add to your bed, you may want to reflect on a couple of things. Just about everyone with a mattress from visco memory foam appears to relish it, they are raving about how they enjoy such great nights of sleep with such perfect support. And who can forget the reality that this foam "remembers" its original form the next morning, and it returns back to it after you arise? All of this is fantastic, but a topper merely may not give you the exact benefits that a complete foam bed could.

What makes a memory foam bed work so great is due to a combination of factors. The top layer of foam is what softens when it comes into contact with body heat, changing to form itself to the contours of your body. But the memory foam in lower levels of the mattress will retain their natural shape and stiffness, as the heat does not get down that far. That quality of support provided by the lower level stems from the high density of the foam, and in some cases it is as dense as 8 pounds per cubic foot. This very firm support is just as crucial to the way in which the memory mattress functions as the softening and changing of the upper level.

This is where the memory foam mattress topper merely may not do as well as a entire mattress. Your original bed will have to be very firm indeed if it is going to provide anywhere close to the underlying support the topper would get from a visco memory foam mattress. And your original bedding should be altogether flat as well, because if it is sagging anywhere, then the foam mattress topper is certainly going to sag in those places as well. All the health and sleep benefits are possibly going to disappear completely if the original mattress has such defects.

All of this means that you may want to think twice about just purchasing a memory foam mattress topper and placing it on top of your regular mattress. Unless you have already got a very stiff mattress, that is completely flat with no sagging to be found anywhere, then the foam in the topper will not have enough support underneath to give you with the benefits of the best memory foam mattress. If you are going to spend the cash anyway, you may as well go for the entire mattress. That might just be preferable to not getting all of the benefits you were wishing for.
