Casper Eastern King Mattresses
At Mancini's Sleepworld, we're proud to carry Casper King mattresses, a perfect fit for sleepers who want maximum width and the brand's full suite of cooling and support technologies. The Eastern King measures 76 inches wide by 80 inches long, offering the widest standard mattress size and making it ideal for couples who each want generous personal space.
Casper King mattresses are built with the same purposeful engineering as every model in the lineup. AirScape™ foam and breathable cover materials promote cool airflow, ZonedSupport™ provides targeted alignment, and hybrid models include individually pocketed Flex Coils for responsive support and reduced motion transfer, both key factors when two sleepers share a mattress.
Whether you are upgrading your primary bedroom or want a spacious sleep surface without the added length of a Cal King, a Casper King mattress delivers cooling comfort across a wide sleep area. Visit a Mancini's Sleepworld showroom to explore the options in person, or take the SleepMatch quiz online for a personalized recommendation.
Frequently Asked Questions
"What makes Casper mattresses worth it?" you ask? Casper mattresses combine advanced cooling technologies, purposeful foam layering, and responsive ergonomic support. In the King size, the widest standard mattress available, those qualities extend across a generous 76-inch-wide sleep surface, giving each sleeper ample room and individual comfort.
Casper's AirScape™ foam circulates air through precision-drilled perforations, while ZonedSupport™ aligns firmer support under your core with softer cushioning at your shoulders. In hybrid models, individually pocketed Flex Coils minimize motion transfer, a major benefit for couples sharing a bed.
For customers in the San Francisco Bay and Sacramento area seeking a spacious, cooling mattress that supports both partners, a King Casper mattress is a strong contender.

A King Casper mattress typically lasts between 7 and 10 years, depending on the model and care.
Since King mattresses are typically used nightly by two sleepers, they can experience more wear than smaller sizes. Casper's high-density CertiPUR-US® certified foams and individually pocketed steel coils in hybrid models are built to resist sagging and hold their shape. Industry Experts recommend assessing your mattress every 7 to 10 years to ensure it still provides the support your body needs.
