With 40% more support coils and more pressure-relieving foam than Harmony models, this mattress offers consistent head-to-toe support and advanced motion isolation for you and your partner. InfiniCool MAX provides our maximum cooling with three layers of active cooling to help you sleep comfortably throughout the night. We've created a lush sleep surface made with up to 100 plastic bottles hand collected from coastlines and ocean-bound waterways. Featuring a lofty, quilted pillow top perfect for those who prefer a lifted feel, this premium mattress ensures your rest is rejuvenating and helps contribute to cleaner water.

Take your rest to the next level with an easy-to-assemble, best-selling adjustable base that features upgrades for enhanced customized comfort. Customize your sleep with Serta's best-selling adjustable base. Now upgraded with a zero-gravity preset for a weightless, calming experience that helps relieve pressure points and USB A and C ports, so charging your devices in bed is even more convenient. A wireless remote easily raises and lowers the head and foot of the mattress so you can find the perfect position, while a preset one-touch flat button quickly and conveniently returns the mattress to a flat position. With 4-in-1 adjustable legs that help ensure the perfect height for your existing furniture, this easy-to-assemble base is an updated shade of navy blue. Now sleeping, relaxing, or working from bed can all be done with maximum comfort-plus, it provides excellent support for parents feeding or holding infants while in bed.
