Marvelous Middle®
The Marvelous Middle® features thicker gauge, individually wrapped coils in the center third of the mattress that equalize pressure distribution across the entire mattress while delivering resilient, reliable support where it’s needed most.
TempaGel reduces tossing and turning, moderates temperature variances, and buffers sensitive pressure points, which improves circulation.
Superedge Plus™
Superedge Plus™
Superedge Plus™ is exceptionally firm foam that resists sagging and surrounds the perimeter of your mattress for edge-to-edge support.
Soft-Cool Finish
Wicks moisture and heat away, giving you a healthy sleep surface.
