Ticking – The outermost layer of mattresses is usually made with a cotton–polyester blend. Serta® mattresses are made of highly woven damask covers. Some premium models offer organic cotton covers treated with aloe for a luxurious feel.

Quilting and Top Padding – Mattresses have a few layers of padding underneath the ticking. Most mattresses have quilting made of foam or batting. Batting provides uniform softness. Serta® high–quality mattresses are made with luxurious blends of high quality anti–microbial micro fibers and KoolComfort™ for the ultimate in comfort leading to a deep, cooler sleep. This greatly assists in absorbing and releasing heat as and when needed. It's perfect for the changing weather conditions. Advanced Comfort Quilt™ (Perfect Sleeper, Perfect Day) is a unique quilt layer is especially tailored to cushion every part of the body while improving circulation at the shoulders, arms and hips. Advanced Comfort Quilt™ is perfect for minimizing tossing and turning for a comfortable sleep.

Middle Padding – Middle padding usually starts with convoluted foam, which feels softer than a flat slab of the same foam type. Convoluted foam spreads weight over a wider surface area, and the result is enhanced comfort. Other padding options include garneted cotton (thick wads of batting that provide loft but compress quickly) and more foam layers of varied thickness and density. Serta® mattresses offer great combinations of high–resiliency foam, latex core, and latex topper. The different layers of foam provide support and cushioning to give you the best sleep possible. KoolComfort™ (Perfect Day) is a luxurious 2 1/2" layer of Serta® exclusive memory foam gives you superior support and pressure relief. Numerous cushions of this foam work in unison to wrap you in comfort while dynamically drawing heat away from your body for a cooler, more restful sleep. It works like a charm, because of the unique open–cell structure of this foam that allows it to breathe up to 95% more than other foams. It also retains its durability throughout the life of the mattress. Ultra–Fresh anti–microbial protection is engineered into this foam and makes it a very hygienic and healthy option.

Insulated Padding – Insulated padding lies right on top of the springs to prevent them from being felt while you sleep. Common insulated fabric materials include matted fabric, plastic fibers, and coco padding (made from coconut husk fibers). Coco padding makes mattresses feel stiffer. Alternatives include plastic webbing and metal grids that may lie directly on top of springs to prevent them from destroying the pad above.

Extra Support – At the edges of the mattress extra dense foam adds extra support to the mattress, giving you a good place to sit and put on your slippers in the morning. Foam Encasement (Perfect Sleeper, Perfect Day) is exclusive to Serta® and offers the edge support of this advanced and encasement design. This durable design gives lasting strength while extending the sleeping surface and eliminating edge 'roll–off'.
