Sealy Nero Mattress Collection
Comforts of Foam. Several different types of soft, supportive foam make the Sealy Nero mattress collection a comfort to come home to. The three different high-density StayTrue® foams contour to your body's shape to encourage proper body alignment and to reliably support you, night after night, year after year. All foams used in the mattress are CertiPUR-US®-certified, which means they're good for your health, durable, resistant to body impressions and pressure-relieving.
