Description The Sealy Advantage Range combines an alternating CoreSupport System with premium comfort layers to provide the body with support that stands the test of time. The Yarley Plush features premium wool fibre and convoluted super-soft quilt foam for soft breathable comfort, and a combination of super-soft, premium and Sealy comfort layers for a luxurious soft feel. It also has a gel centre third layer that conforms to the body for enhanced pressure relief and twice tempered CoreSupport System that provides deep down support engineered to stand the test of time. UniKey reinforces the mattress, extends the sleep surface and provides a stable seating edge, while a spacer gusset promotes air circulation and breathability to regulate temperature, and antimicrobial treatment HealthShield helps maintain a clean and fresh sleep surface. It’s also Australian made and has a 10 year guarantee.
