What most of the people do these days is that they don't buy memory foam mattresses due to the fact that it is quite an expensive deal. They rather prefer to buy a memory foam topper that can be placed on any firm mattress. In this way, they can avail the benefit of memory foam and at the same time economise.

You need to pay attention while choosing a topper also called visco elastic mattress topper. We need to look for a top layer having a density of at least 4lbs/cf with open cell polyurethane memory foam. You also need to check it if it is comfortable. This is one of the most important criteria while selecting the top layer for memory foam mattress.

To ensure that you get comfort in hot and humid months as well, look for a top layer that comes along with a wicking cover. The next thing that you need to focus on is the size and thickness of visco elastic foam mattress. Size is a personal aspect that you can actually decide by yourself but a memory foam mattress that is 3 inches is quite good and anything beyond it will dramatically increase the cost.

Temperature sensitivity is next important thing in priority that you need to check out before placing the order for the memory foam mattress topper. Temperature sensitivity feature enables the mattress to adjust itself according to the temperature. When your body temperature is high, it absorbs heat and softens and this is what happens in the summer months whereas in winters, as the temperature goes down, the visco elastic foam mattress becomes firm. So, look for only those mattresses that have the feature of temperature sensitivity.

To conclude, these are a few things that you need to bear in mind before making the final selection of your Memory Foam Topper.
