Shop Serta King Extra Firm Mattresses

mattresses_serta_king_extra-firm

The Serta extra firm king mattress, measuring 76” wide by 80” long, is large enough for a couple to sleep comfortably, even with a small child or pet. Extra firm mattresses are optimal for support, as the added stiffness allows for excellent spine alignment. When pressure is on the bones, muscles are freed, improving circulation by allowing arteries and veins to relax. For stomach and back sleepers, extra firm mattresses are a dream.
