There is no denying the total comfort offered by the sea of soft yet supportive foam that forms the Excelsior mattress. Because of the responsiveness of the memory foam to body heat, the Excelsior will ensure a snug and warm night's sleep to everyone. This however is the one word of caution in relation to this bed, because you're either someone who likes being very warm in bed at night or you're not. If you're not then the pocket sprung divan beds we sell, or even the divan beds made from a thinner layer of foam and a more traditional spring unit would offer a cooler night's sleep. If however, you're someone who loves being warm and snug in bed on those cold winter nights and even on summer nights then you will love the Excelsior!
