What is the best thickness and density for a memory foam mattress?
After extensive research it is our conclusion that generally the most suitable thickness is 7 cm(2.8″) supported by a 13 cm ( 5.1″) premium high density foam, giving an overall depth of 20 cm (7.9″). The memory foam should have a density of 60kg cm3/4lbs. cft. Less might not be suitable, more is excessive and becomes too expensive.
