    If the term “split king mattress” had you thinking about the 1960s sitcoms where couples used to sleep in two individual beds, then you are totally wrong. A lot has changed in terms of bed technology after that. Things are much more sophisticated now and in fact, have made our sleeping lives better.

    Mattresses that you see in the market today are far more supportive and adjustable. So, we have really come a long way from those straw-filled cotton sacks on wooden slats. However, with advances, the way we sleep has also become more complicated.

    Choosing the right mattress for your needs can turn out to be perplexing at times—especially if you are unfamiliar about the different terminologies used. Speaking of them, one such is “split king.”

    Though split king mattresses aren’t the most common types of bed configurations, they still may be an ideal option for couples with completely different sleeping choices. But fret not because you can own a good split king mattress and yet cuddle with your darling.

    What is a Split King Mattress?

    A split king mattress is 2 twin-size mattresses that’s put together in a way that it forms a big king-size bed. Although the exact measurements may differ, most split king mattresses you find will use the twin XL size in order to make a 38″ x 80″ footprint.

    Both the twin-size mattresses are fixed together via a connector (though the making can vary) and can be easily split apart whenever required. Thus, the name “split king.”

    One of the main advantages of this mattresses is that they prevent midnight sprawl. So, no more saying “hey, you are on my side of the bed!” Interestingly, the motion transfer is so less that you don’t have to be worried of your bedmate’s tossing-and-turning.

    How Does it Work?

    The next obvious question you might have is about its foundation. So, if the bed consists of 2 twin-size mattresses, then does it also have 2 twin-size bases or it’s just 1? Or perhaps, something different completely?

    Interestingly, mattress manufacturers will have a readymade solution like split king adjustable beds, which are exclusively designed to accommodate both the mattresses. So, it’s up to you if you want to add the adjustability or not.

    Since you have 2 individual halves, adjustability can become a better and an attractive feature. Why? Well, you can comfortably sit upright to work on your laptop while your honey snoozes. Yeah, you can still enjoy the perks of a split mattress without this feature too.

    When Should a Split King Mattress be Used?

    These mattresses allow couples to personalise their sides of the bed according to their sleeping preferences and further, prevent sleep disturbances.

    Let’s say your partner is a stomach sleeper that needs a tight or firm mattress and you, on the other hand, is a side sleeper that needs a nice, soft mattress, then a split king bed is what you two will need because it lets you have a healthy sleep while still being close to your partner.

    Overall, these mattresses is the only solution, which accommodates completely different sleeping choices between two people or partners. So, two partners with different bed habits, sleeping positions, and preferences for mattress firmness can comfortably sleep if they have a split king mattress so that they aren’t disturbed.
