Personally, having tried out both a Sealy Posturepedic mattress and a Restonic I could not say one was more comfortable than the other. Also, having done some research about consumers who bought both, it was impossible to say which was better over the long term.
When buying the mattress, you should ask the salesperson whether you can try lying down on it to know how it feels. Some shops may not allow this, but you should be adamant about it because it is your right as a customer to try the product before making a purchase.
The four "stages" of the Product Life Cycle are historically referred to as: Stage 1 or market development, Stage 2 or market growth, Stage 3 or market maturity and Stage 4 or market decline.
Some other types of mattresses are made of latex foam or memory foam. These can be purchased in different densitiesthe higher the density, the more firm it is.
