When purchasing a memory foam mattress one of the biggest problems is deciding what is the best thickness of memory foam. Their is no need to purchase a memory mattress with too much memory foam as this will cost more, and will provide no more support or comfort. If it is for a child then 5cm of memory foam is ideal, if you are under 13 stones then 7cm will be ideal, if you are over 15 stones then you will probably need 10cm of memory foam. Some retailers only sell a memory foam mattress with 2.5cm of memory foam and this is not really ideal unless you are a young child.
