The three-zone inlay with foam provides "a basic foam at your shoulders and knees, and a super soft foam in the center, near the hips," according to the Sealy website. People who prefer to feel like they're sleeping on a cloud may like this bed the best. The three-zone inlay with memory foam offers memory foam in the middle section. This results in "even better pressure relief near the hips," according to Sealy. Lastly, the seven-zone inlay with memory and latex foam provides support at the shoulders and knees by using memory foam. Latex foam in the center offers "the best pressure relief near the hips," notes Sealy. Those who do a lot of tossing and turning during the night may find that they like this bed the best, suggests the manufacturer.
A bed's innersprings keep your spine properly aligned with the rest of your body. You can get a Posturepedic bed with 736 supportive coils (for a queen size), which offers basic orthopedic support for your back. A second option is to get the 782 coil system bed (also queen size), which according to Sealy, makes "it the best Sealy Posturepedic for orthopedically correct support."
The edge of a bed allows you a place to sit without sinking into the middle. The Posturepedic bed comes with two different types of edging. The unicased edge system uses patented technology to reduce "the back-and-forth sway of the mattress." This means you won't have to perform a balancing act when sitting down to put on your socks or when sleeping toward the edge of the bed. The second option is called the unicased XT edge system and is "Sealy's newest invention," meant to ensure that the edge of the bed feels every bit as good and supportive as the center of the bed.
