The Stassi Mattress delivers a firm, supportive sleep surface designed for those who prefer a more stable and responsive feel. Part of the Sealy Posturepedic® Plus Copper Series, the Stassi combines targeted support with comfortable cushioning to help promote proper alignment and dependable comfort throughout the night.

Responsive pocket coils form the supportive core of the mattress, adapting to the body while providing durable stability and helping the mattress maintain its shape over time. Carefully selected cushioning layers add conforming comfort without taking away from the firmer feel, creating a balanced sleep surface with consistent support where it matters most.

A cool-to-the-touch cover helps create a more comfortable sleep environment while an antibacterial treatment helps maintain a fresher sleeping surface. Combining responsive pocket coil support, cushioning comfort, and cooling materials, the Sealy Stassi is a thoughtful choice for anyone looking for a firm Sealy mattress with reliable night-after-night performance.
