How often have you heard someone tell you "I must have slept wrong last night"? If their complaint is a sore neck or an aching back, they're probably right. Here's why. Your mattress needs to provide the right amount of support at each pressure point on your body to keep your body properly aligned. If the mattress is too soft, it allows heavier parts of your body to sink deeper, pulling your spine out of alignment. And when your spine is out of alignment, it's tugging on all of the muscles that are connected to it. That's why sleeping out of alignment leads to "cricked neck syndrome" or worse. If the mattress is too firm on the other hand, it puts pressure on delicate tissues, leading to that bruised feeling in your hips, shoulders and heels. Your mattress has to figure out which parts of your body need that little extra oomph underneath them to keep them from sagging and pulling on all of your muscles. Since everyone's body is different, there is no "one size fits all" solution to the problem. That's why the Sealy mattress company makes so many different types and styles of mattresses. Whether you prefer a memory foam or inner spring, pocketed coils or linked coils, Sealy has just the right mattress for you.
