What is The Difference between a Memory Foam Mattress and Foam Topper/Mattress Pads?
There is a significant difference between a memory foam mattress and a foam topper.
In regards to the mattress pad/topper, the topper is literally placed on top of your existing innerspring mattress. This layer will give a bed the feel of a memory foam mattress; however, in many cases the results may not be so good. The reason is that many mattresses are not firm enough to give the same feel as a memory foam mattress. Many mattresses are considerably older and dip in the middle and so on.
The result of a memory foam topper placed on top will be a similar effect. The firmer the mattress beneath the mattress pad, the firmer and more like a real memory foam mattress it can be. Also, since the case would be dipping in the middle, in response to the older mattress, one possibility to overcome this would be to purchase a firmer, denser memory foam topper/pad. There is no guarantee that this will alleviate the situation, but it has worked for some individuals who decided to try a memory foam topper first before they ended up purchasing their first visco elastic mattress.
Another pitfall that may need to be overcome if you decide to purchase a thicker, denser foam mattress pad would be which bed sheets to use. This has posed a problem for many people in the past due to the fact that bed sheets are basically produced to cover a ten-inch mattress. If the added topper is more than that of the capacity of the bed sheets then either search for larger bed sheets or make sure the memory foam topper pad is within the range of the bed sheet span. This, of course, can be evaluated by simply using a tape measure or any other type of measuring device. Again, if the mattress is older, feeling lumpy and dipping then a 1-inch topper may not provide the best results when using a memory foam topper.
