Memory foam is of a very dense construction. Memory foams' molecules are especially small and very tightly packed. Memory foam mattresses are very difficult to clean since they are not designed to be turned over.

     If you own cats or dogs you should consider the difficulty in cleaning before purchasing a memory foam mattress. Sooner or later even the best pets will get around to urinating all over your expensive memory foam mattress.

     Memory Foam Mattresses should always have a quality mattress pad to prevent any bodily fluids from accidentally soiling the mattress cover from leakage.

     Memory foam mattress warranties are very restrictive. The memory foam mattress manufacturers examine the mattresses covers very carefully for signs of any human or animal bodily fluids before agreeing to accept the memory foam mattress back as a warranty return.

     If you own pets you should seriously consider purchasing a conventional mattress.
