Cobalt Firm

Comfort and support are in perfect harmony with the Sealy Posturepedic Premier Hybrid Cobalt Firm mattress. The hybrid half foam-half springs construction combines the body-conforming contour of memory foam on top with the firm support provided by specially designed springs underneath.

The top half consists of three layers, starting with a layer of SealyCool Gel Memory Foam to provide pressure point reduction and help maintain a comfortable sleeping temperature. The next layer is SealyCushion Extra Soft Foam for additional body contouring followed by another layer of SealyCool Gel Memory Foam to help provide additional support for the lower back area. These carefully matched layers of foam designed to provide long-term comfort without the “sinking feeling” associated with soft mattresses.

The bottom half base layer is the Zoned Sealy Embrace Premier Coil system, which uses a series of individually wrapped coils to provide the deep down full-body support of a traditional innerspring mattress.

A peaceful night’s rest and a rested good morning are the most popular benefits of Sealy Posturepedic Premier Hybrid Cobalt Firm mattress—a marvel of sleep technology.

My wife and I were about to start sleeping in separate beds before we found the Sealy Hybrid Cobalt Firm mattress. My tossing and turning not only bothered her sleep, it made sure I woke up each morning feeling like I had been working all night. Every mattress we tried was too soft or too firm for one of us. But just like Goldilocks in that three bears story we finally found one that was just right.  The Cobalt Firm with it double layers makes it so I can get a cool nights sleep without all the flopping around, and for me, cool is  especially important. Also, when I do move around in my sleep my wife can hardly feel it. Now she sleeps through the night and we both feel good when we wake up in the morning. Makes for a better marriage!
