The Serta® Perfect Sleeper® Elite Adrift Mattress is designed with zoned comfort to support undisturbed sleep while delivering a firm, structured feel ideal for proper spinal alignment. It is well suited for back and stomach sleepers who prefer a stable and supportive sleep surface. At its core, the exclusive 1600 Elite Comfort 5-Zoned Coil System features individually wrapped coils arranged in targeted zones to provide reinforced support through the centre of the mattress. A responsive microcoil layer enhances contouring while maintaining firmness, and motion separation foam helps reduce partner disturbance. Serta® Gel Foam layers provide enhanced pressure relief and promote airflow, while EXCLUSIVE ComfortCool™ fabric delivers a cool-to-the-touch feel the moment you lie down. EXCLUSIVE Serta® SilverPur™ Fibre helps maintain a fresh, breathable sleep surface for lasting comfort. Best Edge® Foam Encasement reinforces the perimeter for consistent edge support and increased sleep surface. Compared to the Becalm and Cruise models, the Adrift offers the most structured support with minimal sink, making it the firmest option in the collection.
