King Vs Split King: What Are The Differences?

While a split king bed is made up of two twin XL mattresses joined together in a single bed frame, a king bed has a single solid mattress. Let’s see which is suitable for you!

Size and room space

In terms of length, both king and split king measure 80 inches per mattress that ensuring ample space for taller people to stretch comfortably.

When it comes to width, the king-size mattress is wider, measuring 76 inches. Meanwhile, the split king offer two separate mattresses, each measuring 38 inches wide. 

Then, considering the suggested room size, both require 12 x 12 feet. This requirement ensures enough space to move around the bed and allows for another furniture placement.

In short, the king mattress size is wider. But both need the same room area, so they are suitable for bedrooms of similar size.


The king size is ideal for couples and an additional person (a child who sometimes sleeps with a parent or a pet). The spaciousness allows people to sleep comfortably without feeling cramped.

Similarly, the split king mattresses are also more suitable for couples with different sleeping preferences. With the ability to customize the firmness on each side, it meets each individual’s comfort needs.


Overall, the flexibility offered by a split king size is superior to a traditional bed. 

Specifically, the split bed allows sleepers to adjust it to their preferences without compromising their sleeper’s comfort, unlike a single-size mattress. This feature is especially beneficial for couples with different sleep needs.

For example, if one partner prefers a firmer option while the other prefers a softer one, they can choose their own preferred firmness level. This customization ensures that both people can sleep comfortably and wake up refreshed.

In addition, the adjustable bed frame can be paired with a split mattress to enhance comfort. With its base, you can change the bed’s height to your fitting. 

Whether you want to sit up and watch a movie or adjust the bed’s foot to read, it can all be done without disturbing your partner’s sleep.


Currently, a king mattress will range from about $1,350 – $2,600. Meanwhile, the split king size has quite an expensive range from about $1,700 – $3,900.

In fact, the split design includes two separate mattresses, increasing the overall cost. Also, its customization options, such as adjustable stiffness or personalized comfort settings, contribute to the higher  price.

It’s worth noting that the specific prices for both sizes can vary depending on the brand, retailer, material, features, and any promotions available at the time of purchase. 

Thus, you should compare prices from many sellers and consider the overall value, including their quality and features, before making a purchase decision.
