Rally Firm Mattress - King
From the years of innovation that have lead up to its inception to the materials used to construct the mattress, the Rally Firm Mattress - King is designed to give you the most comfortable sleep you've ever had. This mattress features the firmest mattress feel of the Rally Mattress collection.
These mattresses use a combination of advanced, conductive materials, ventilation and open cell design to actively move heat away from the body and our the mattress. That's what 70 years of experience working with world leading foam scientists will do.
Top layers of custom designed Rally Cool Bounce Copper Gel and advanced fast recovery memory foam create a buoyant, responsive structure that contours to your body without sucking you in.
