What is the best mattress? One that supports you in perfect comfort all through the night as you change positions, and continues to do so for many years with no noticeable decline in quality.
So there are really only two main points to consider: comfort and durability.
Of course each person’s definition of these qualities is unique to them. What one person finds deliciously comfortable, another may find nearly intolerable. That’s why it’s so important to test everything to make your own mattress comparisons.
