King Split Head King Queen Split Head Traditional Serta Mattresses

King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Traditional mattresses have a tight-top surface — the comfort layers are smoothly upholstered into the mattress with no added pillow-top or euro-top. That means a firmer, more supportive and responsive feel, excellent durability, and a clean classic look without the "sink" of a plush topper. Compare every tight-top option below by brand, feel, and price.
