What should you look for in a mattress? Three things: comfort, support, and durability, from a brand you trust. It's that simple. Comfort, is a matter of personal preference. What feels comfortable to one person may feel uncomfortable to another person. Therefore, whoever is going to use the bed should try several different models before making a purchase.
The UPHOLSTERY of the mattress determines surface comfort. Upholstery† refers to the various layers of material between your body and† the innerspring. Both the type and thickness of these materials will produce different levels of feel and therefore different degrees of comfort.
Sealy Posturepedic mattresses sleep systems offer correct back support regardless of firmness. The myth "firmer is better" is not necessarily true. Your body type determines what comfort is better for you.
A mattress that's too firm for your body will not support all parts of the body evenly, and may cause discomfort at the body's heaviest parts, the shoulders and hips. The increased pressure on these points reduces blood circulation and will cause tossing and turning. This may result in a poor night's sleep and a far less productive day.
Durability is very important. The type of upholstery materials, and the type of steel, and the design of the innerspring impact the durability of the mattress. For example, the coil systems are heat tempered twice, which helps maintain their shape so they last longer.
The box spring, however, provides the greatest measure of durability in a sleep set. It absorbs the major portion of stress and weight placed on the sleep surface. It works much like a "shock absorber" in a car's suspension to eliminate stress in the mattress unit and prolong the mattress comfort life.
When searching for the best mattress, perhaps the most important thing to remember is that mattresses are largely a matter of personal preference.
