A lot of mattresses look comfortable on the showroom floor but they are not after you use them for a year or two. If your mattress is not made with the right durable materials then that comfort will not last. If you want Real Comfort, that will last, then you should get to know your foam first. And the difference between what is real and what is fake comfort. Fake comfort is seat cushions or mattresses that are made with lightweight foam and fluffy fibre that will sag pre-maturely and leave you sinking into them.
