Transform your bedroom into an oasis of comfort with this Serta iComfort Blue 300 plush pillowtop hybrid king mattress set. Layers of TempActiv gel memory foam and EverCool Fuze gel foam cradle your body while you sleep for enhanced comfort and pressure relief and help encourage airflow to dissipate heat. The TempActiv balance fabric cover ensures efficient heat-and-moisture regulation, helping you stay cool, dry and comfortable all night.

Featuring a Hybrid Coil system, this Serta iComfort Blue 300 hybrid king mattress provides exceptional support and helps keep your body in a neutral position. The medium firmness level lets you sink into bed while keeping your spine aligned and supporting your hips and back, ideal for back and combination sleepers.

This Serta iComfort Blue Fusion 300 mattress set includes two 5.75-inch standard box springs or a 9-inch StabL-Base low-profile box spring. The two available sizes give you options for customizing your sleeping area, and the sturdy designs offer consistent support. Mount the mattress on a Serta adjustable foundation (not included) to enhance your sleeping area with both head and foot lift functionality for watching TV or reading comfortably in bed.


iComfort Hybrid CollectionThe Serta® iComfort® Hybrid is the only mattress that combines the cooling memory foams of the iComfort sleep system with the newest and most advanced coil support system. You get all the perks in one bed—cooling technology, deep down support and cradling comfort.


Compatible with Serta Adjustable FoundationsWhether you like to watch television, read or just relax in bed after a long day, Serta’s adjustable foundations (sold separately) customize your mattress. Choose from the Custom II Foundation that raises the head of the foundation up to 90 degrees for comfort and support, the Motion Essentials II Foundation that features Smooth Power™ Lifting System for head and foot lifting functionality, or the Motion Select Foundation that offers ultra-quiet massage, programmable head and foot positions, plus adjustable leg lift.
