Knight Extra Firm Mattress & Boxspring
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.
The ventilated, flexible, and resilient Airflow™ border allows air to circulate throughout the night, keeping your mattress temperature-neutral while also delivering ventilated support.
Superedge Plus™ is exceptionally firm foam that resists sagging and surrounds the perimeter of your mattress for edge-to-edge support.
Set includes Mattress and White Box Foundation
