Serta King-Size Specs

Innerspring Support

• An innerspring support system offers proper spinal alignment while a cushion over the coils provides a layer of comfort while a person sleeps. The Perfect Sleeper is Serta's best-selling model, and the king size in this style provides 648 coils. The Vera Wang and the Trump Home line offer greater support, with approximately 992 coils depending on the model number, additional top cushioning and total edge foam encasement. The Trump Home Luxury and the Serta Perfect Day mattresses are the company's premier models for innerspring support, with 1176 coils for the king size and 1148 for the California king.

Latex Foam Support

• Rather than the traditional innerspring support system, the Vera Wang Specialty and Serta Pure Response mattresses feature breathable, resilient Talalay Latex Foam support. This material is a blend of synthetic and natural latex for durability and optimal performance. Additionally, Serta believes the Talalay process is capable of producing a firmer foam than other latex processes. Individuals with allergies or sensitivities often choose latex-foam mattresses since they are naturally antimicrobial, hypoallergenic and dust-mite resistant.

Memory Foam Support

• Memory Foam mattresses provide a visco-elastic support system that conforms to body contours during sleep. People who toss and turn uncomfortably throughout the night may benefit from a Memory Foam mattress because it takes significant weight off pressure points. Motion transfer is also reduced so your partner isn't disturbed if you switch positions. The Vera Wang Specialty mattress is available in Memory Foam, as is the Serta True Response.

Foundation and Warranty

• All Serta king mattresses offer a StabL-Base Foundation, which provides dependable support across the bottom of the mattress and a longer life to the sleep set. This construction also helps isolate the impact of your partner's movements so you can sleep undisturbed all night long. Serta mattresses come with either a 10-year or 20-year limited warranty.

Delivery

• Since king-size mattresses are difficult to maneuver through narrow halls and doorways, Serta recommends that you opt for the store's delivery services with a new purchase. Do not bend a mattress in an attempt to squeeze it through a tight passageway. Serta king-size mattresses are sold with split box springs, making it easier to move them through narrow spaces.
