Perfect Hybrid Mattress

[This review was collected as part of a promotion.] This Serta mattress has a beautiful design pattern. It provides proper support no matter if I sleep on my back or on sides. The mattress actually has firmness that I was expecting, other mattresses I’ve used in the past deforms memory foam overtime with weight. Hybrid technology indeed brings best of spring and memory foam mattress together.
