There is a huge difference between a memory foam mattress vs. a mattress that just has memory foam in it. Many mattresses on the market today have a layer of memory foam inside which claims to help in dispersing heat and keep you sleeping cooler.
The reality is that you may not actually see a huge benefit unless the memory foam layer is near the top, and thick enough to help disperse the heat.
Memory foam mattresses on the other hand almost always have a memory foam layer at the top which is at least 2 inches in thickness. This ensures that the gel in the memory foam actually helps to disperse the heat from your body, and the layer is thick enough so that you can feel the pressure relieving and body conforming benefits of the memory foam itself.
