Sealy Cal King Mattresses

"What makes Sealy mattresses worth it?" you ask? With over 140 years of expertise and recognition as America's \#1 Mattress Brand, Sealy delivers targeted support and trusted comfort. A Cal King Sealy mattress is engineered to promote proper spinal alignment and provide consistent, all-night support in the longest standard mattress size.

The Cal King measures 72 inches wide by 84 inches long, making it an ideal choice for taller individuals or anyone who values additional legroom. Sealy's PrecisionFit Coils provide consistent support across the entire sleep surface, even in this larger format.

A Cal King Sealy mattress typically lasts between 7 and 10 years, depending on the collection, materials, and care. Models with advanced coil systems and premium comfort layers tend to maintain their structure toward the longer end of that range.

Experts generally recommend evaluating your mattress every 7 to 10 years. Sealy's PrecisionFit Coils and reinforced edge systems help these mattresses resist sagging and retain their performance over time.

For customers across the San Francisco Bay Area who want reliable performance in a larger size, a Cal King Sealy is built to deliver.

Sealy offers several Posturepedic collections, each engineered at a different level of support and comfort while maintaining the brand's signature PrecisionFit Coil technology.

The Posturepedic Pro Collection provides premium comfort layers in innerspring and hybrid configurations.
