The first time you walked into a store to get a mattress, you thought it was straight forward. The knowledge of the types of mattresses is not something you take an interest in until you have to buy one. The problem begins when all this technical stuff about good sleep, better health, and a quality mattress start to be thrown at you. It is essential to know that all these things are relative. Do not get bogged down by all those salesman antics. Understand what you want and go for it.
