Serta Perfect Sleeper Calming Nights 13" Firm Mattress

The Serta Perfect Sleeper Calming Nights is a 13" firm innerspring mattress built to deliver dependable support and cooling comfort for sleepers who want more lift and less sink. Ideal for back and stomach sleepers who prefer a firm, supportive feel, its combination of Cool Twist® Gel Foam and Zoned Gel Memory Foam works with a wool fiber comfort layer to support the body where it’s needed most, reduce pressure, and keep things cool and comfortable all night long. Serta® Support Foam adds an extra layer of steady, even support across the entire mattress 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.
