To begin with, the Serta Kendall plush queen mattress greets you with a CoolFeel® smooth-knit cover that feels cool at first touch. Next, graphite memory foam joins Cool Twist® Gel Memory Foam, creating a cloud-like soft sleep surface that side sleepers call the best plush hybrid mattress for side sleepers. 

Because these foams rest on a five-zone gel-foam band and a core of individually wrapped pocketed coils, you still receive targeted pressure point relief and balanced mid-body support that can ease hip or shoulder tension. 

Moreover, each spring flexes on its own, delivering advanced motion isolation for couples even when one partner changes position. 

Finally, Cloudy Mattress ships every order free across the United States, offers easy financing, and knocks $900 off during the Memorial promotion—so you can buy a Serta Perfect Sleeper X online and upgrade to a plush, 13-inch soft hybrid mattress without leaving home.
