Serta Perfect Sleeper Calming Nights 13.5" Plush Mattress

The Serta Perfect Sleeper Calming Nights is a 13.5" plush innerspring mattress designed to deliver balanced support with soft, pressure-relieving comfort—a perfect match for side and combination sleepers who crave a cushioned, body-hugging feel. An extra 2" layer of CushionGel™ Foam, a pressure-relieving foam infused with cooling gel, gently contours to the body, while Cool Twist® Gel Foam and Zoned Gel Memory Foam work together to support the body where it’s needed most and ease pressure points throughout the night. A wool fiber comfort layer adds breathability and an additional layer of comfort, and Serta® Support Foam delivers steady, even support across the entire surface. The Q4™ Support System with Best Edge™ Foam Encasement provides strong, lasting support, reduces motion transfer, encourages proper spinal alignment, and creates a more stable edge so you can enjoy every inch of the bed. Built-in antimicrobial protection helps keep your mattress fresh, while the CoolFeel™ Fabric cover pulls heat away from the body for a cooler, more relaxing sleep surface. Mattress protector recommended. Compatible with an adjustable base or foundation sold separately.
