Dual Eastern King

Best Dual King Size Waterbed Mattress

If you're treating yourself to a new bed or indulging in the idea of something nicer - like a dual king-size waterbed mattress, you've probably seen a few different terms for a dual king bed, including an Eastern king bed.

An Eastern king is simply another term for a regular king mattress used to differentiate itself from a California King Size Mattress. So, in general, there are only two types of standard king size beds, which also apply to waterbeds:

  • King aka a standard king, traditional king, or Eastern king
  • California king aka the Cal king or Western king

Dual king-size waterbed mattresses are a luxurious, customizable, and advanced sleeping solution that is just perfect for some people. It's a unique and slightly more complex bed choice than your single standard king, so it requires some research and testing before you commit. That said, the added benefits make a dual king bed worth the effort.

One of those often-heard and often-misunderstood terms is "split king." Most people understand that it's a bed type, but what, exactly is it, and why should you consider getting one?
