King mattresses are a great solution for the master bedroom, as the extra room can create a more luxurious sleep experience. Couples sleeping on a king mattress with different comfort preferences can choose to use two Twin XL mattresses in place of one king mattress. This way, each sleeper has a mattress to meet their specific comfort needs. Serta produces a wide variety of king mattresses featuring both innerspring and all-foam support systems. A Serta king mattress measures approximately 76" x 79.5". These measurements can vary by +/- 1/2". Size availability varies by product and retailer. Mattress heights vary by product, so please see your retailer for information on specific model height. Select retailers offer a special size called a California king mattress for select models, which measures approximately 72" x 83.5". Please see your local retailer about availability of Serta California king, or "Cal king", mattresses.Clear all selections Departments $ to $ Clear all selections $ to $ Clear price
