If you know you want a king-size mattress, the split king is an option worth considering. They both offer plenty of space, but the split king takes versatility and customization to the next level.

With a split king, couples can savor closeness while retaining individual control over their sleep sanctuary. Gone are the days of compromise; now, each partner enjoys their personalized sleep haven.

Choosing the right bed is a critical decision. Let us help you understand the king vs. split king debate so you can make an informed choice.

What Is a King-Size Mattress?

Spanning 76 inches in length and 80 inches in width, the king-size mattress offers an expansive sleeping realm. It's spacious enough to comfortably accommodate a couple, a few kids, and a large dog. The design intent? To lavish couples with an abundance of space.

Comparing the king with other mattress dimensions:

  • Twin – 38” x 75”
  • Twin XL -- 38" x 80"
  • Full – 53” x 75”
  • Queen – 60” x 80”
  • King – 76” x 80”

You might notice that the most significant difference between these sizes is the width of the mattress. For example, when you look at king vs. queen, you see the width is 60" compared to 76". Generally, as mattress sizes increase, they get wider but not necessarily longer. In fact, a king-size mattress is twice as wide as a twin XL.

What Is a Split King Mattress?

Envision two twin mattresses united side by side, yet retaining their distinct identities. This design ensures each sleeper enjoys their personalized space, akin to having individual twin beds, but with the closeness of a shared bed.

The split king mattress size is the same as a king: 76" x 80". The bed is just split down the middle.

    Split King vs. King Bed

    At first glance, king and split king beds may seem similar, but their design tells a different story. 

    A split king bed combines two separate units to form a single bed, offering a unique blend of individuality and unity. This design, while advantageous in many ways, does come with its own set of quirks. For instance, the dual-mattress structure introduces a divide that some sleepers might find slightly inconvenient. However, many of these minor challenges associated with split king adjustable beds can be easily addressed.

    Despite these differences in design, the overall dimensions of both bed types remain consistent. 

    The Cost of Split King Mattresses

    Typically, a split king mattress might carry a slightly higher price tag than its standard king counterpart, even among more economical choices. However, the dimensions aren't the sole determinant of the cost.

    The material composition of the mattress plays a pivotal role in its pricing. For instance, a hybrid mattress often comes with a heftier price tag compared to innerspring or latex variants.

    While size does factor into the cost, it's worth noting that both split king and standard king share identical dimensions. Hence, any price variance between the two, based solely on size, is likely to be negligible.

    Why Might You Buy a Split King Mattress?

    The split king offers a suite of advantages that traditional king mattresses might not, including:

    • Personalized Spaces: Each sleeper can tailor their section as they please, a feature that shines especially with adjustable models.
    • Ease of Handling: Comprising two separate pieces, the split king is simpler to maneuver and rotate.
    • Decorative Flexibility: Using twin XL sheets opens doors to diverse bedding aesthetics.
    • Zero Motion Disruption: A sleeper's movements remain confined to their side, ensuring undisturbed rest for their partner.
    • Custom Firmness: Catering to diverse comfort needs, one side can be plush while the other offers firm support, a boon for couples with contrasting preferences.

    Choosing a Bed that Suits Your Needs

    Choosing the right bed is more than just about size; it's about aligning your sleep environment with your unique needs. A split king offers unparalleled customization, especially for couples with distinct mattress preferences or those who require different firmness levels due to health reasons. If one partner frequently tosses and turns or gets up during the night, a split king can minimize motion transfer, ensuring undisturbed sleep for the other.
