What is a Split King Mattress?

A split king mattress is a two-piece mattress.  When used together, the two sides add up to the same surface space as a traditional king.  Each side is 80 inches long and 38 inches wide.  Combined, the two pieces create a king size which is 76” x 80” the same as what a one-piece king measures.  A conventional TwinXL mattress size is equal to one side of a split king mattress.  Its dimensions are also 38” x 80” so two TwinXL’s equal a split king mattress.

Split King vs Split California King

To know is a split king the same as two twins, we need to refer back to the sizes of beds and mattresses.  You will note there are actually two different Split King sizes as well; the traditional Split-King and the California Split-King.  The Split-King and the Split California King Mattresses are unlike each other in size.  This means while they both require two bases, they will not be made up of the same size base.  When we ask is a split king the same as two twins in reference to the California King, it is not made up of two twin bases at all.

Split King Mattress Sizes

A split king mattress is made up of two mattresses, with each side being a twin xl mattress. Each twin xl mattress measures 38″ by 80″, and both mattresses put together are equal to a king-size mattress, which measures 76″ by 80″. This mattress got its name because it is a king split in half. The split king mattress is usually paired with a split king adjustable bed.

Sheets for Split King Mattresses

Bedding for a Split King mattress can come in a couple different sizes.  A comforter, for example, covers the entire surface so it could be a King size.  The same goes for a flat bedsheet.  However, fitted sheets for Split King mattresses must wrap around each side of the mattress.  This is especially important when the mattress will be used with an adjustable bed because the sides may move separately.  Each side of a Split King is the same size as a Twin XL.  So, a Split King mattress requires two Twin XL fitted sheets.

 

How to Choose a Split King Mattress?

There are some considerations that you should keep in mind when you are choosing a split king mattress. These factors you should consider include warranty, type, price and the type of sleeper to decide on.

Type Split King Mattress

  • Memory Foam: A memory foam mattress is a kind of mattress that is made out of foam. The newest memory foam mattress is designed with cooling features mixed with the foam, graphene foam, or infused gel.
  • Latex Mattress: A latex mattress is a mattress that is made of natural latex inside the mattress. The latex material is extracted from the rubber trees which grow in the tropical region. Natural latex can come in several different comfort levels.
  • Air Mattress: An adjustable air mattress has air chambers to control the mattress’s comfort level. Using the remote control can change the bed’s comfort level.
  • Hybrid Mattress: A hybrid mattress is a kind of mattress that can be made of both latex and coils or memory foam and coils.
  • Warranty: The warranty of the mattress varies depending on the manufacturer. But in most cases, the Kingship Comfort is the mattress brand with a limited warranty of 15 years.
  • Price: The Split King mattress’s prices vary depending on the materials used to make the mattress. The most expensive types of mattresses are latex and air mattresses. They are more costly than other types of the mattress.
  • Type of Sleeper: The type of sleeper matters when purchasing the split king mattress. The combination sleepers, side and back, usually prefer medium comfort, whereas the stomach sleepers prefer the firm mattress.

 

Our Thoughts Based On Split King Mattress

Based on our experience and the feedback of the customers, the Split King mattress is preferred among couples. The Split King mattress, paired with an adjustable bed, enables the sleeper to control their side, or they can get a different comfort level based on personal preference. Buying the same mattress with varying comfort levels is essential if you prefer doing these. The mattresses should be the same height, which will match the bed’s total height.

 

Frequently Asked Questions

 

Do you need a box spring for Split King mattresses?

Rarely is there a need for a box spring for Split King mattresses.  Typically, a Split King mattress is paired with an adjustable bed.  No box spring is necessary in that case.  Also, most of the time when a Split King is used on a platform bed, a box spring is not needed.  A box spring would be used if this size mattress is used outside of an adjustable bed or platform bed.

 

How to keep the two Split King mattresses from moving?

When used on an adjustable bed, the weight of a Split King mattress is usually enough to prevent any moving.  If it is not, retainer bars will hold the mattress in place.  If, for any reason there is still sliding or unwanted movement, there is a solution.  Sometimes people use Velcro tape to adhere the mattress to the base, placing it on the adjustable bed Velcro-side up.  Certain adjustable beds use similar technology to help reduce mattress movement while positioning the bed.

 

Are there Split Top King Mattresses?

Split Top King mattress do exist.  This type of mattress is split in two from the top of the mattress to the center.  From there toward the bottom, the mattress is connected.  It is often used jointly with a Split Top King adjustable bed.  Doing this allows for independent positioning of the upper body on each side but simultaneous movement of the legs.

 

Is a Split King the same as two Twins?

The answer is “no”.  A Split King  is two Twin XL not two Twins. These mattresses or bases are actually quite different in dimensions.  Twin XL stands for Twin Extra Long.  You might guess, this bed is longer than the traditional Twin, approximately 6 inches longer in fact.  A Twin measures about 39 inches wide and 74 inches in length.  A Twin XL however, measures the same width wise but comes in at 80 inches long.  This is an important difference when we are talking about the makeup of a Split King.
