What size is a Split California King mattress?

A split california mattress consists of 2 mattresses sized 36″ wide by 84″ long. These 2 mattresses are pushed together to fit the size of a standard california king mattress which is 72″ wide by 84″ long. 

Split California King vs California King

A split california king is ultimately the same size as a standard california king, simply split in half into two separate mattress pieces.  

split-cali-king-vs-cali-king

What is the purpose of a split California King?

A split cali king or a split mattress of any kind has specific uses that benefit sleepers when compared to a standard single unit mattress. 

Different Comfort Preferences: If 2 sleepers prefer a different type of mattress (i.e. one likes it firm and the other likes it soft) then it can be difficult to compromise and find a mattress that works well for both sleepers. A split cali king mattress allows for each sleeper to choose a mattress firmness or style that works well for them while still sleeping in the same bed. Many of the options below allow for you to choose your specific firmness level. 

Split adjustable base: If you have a split California king adjustable base then you will need to purchase a split California king mattress. A split adjustable base allows each side to move freely from one another. This means one sleeper could have their base positioned in an upright sleeping position while the other could be sleeping or have their legs up. A split mattress coupled with a split adjustable base gives drastically more individual positioning freedoms than a standard single unit mattress. 

What are the different types of split California king mattresses?

Split cali king mattresses are somewhat common and are available in just about every mattress style and every mattress material on the market. 

  • Hybrid: A hybrid mattress is a fancy way of specifying that the mattress utilizes innersprings as well as foam. This gives the sleeper the traditional bounce and support of a spring mattress while also providing pressure relief and comfort properties of a foam mattress. We recommend hybrid mattresses to the large majority of sleepers who don’t have any specific sleep needs.
  • Latex: Latex is known as the most “natural” option when is comes to mattress materials. Latex is poured form the rubber tree and is made without the use of harsh chemicals or additives that other products are made with. It is important to note that there are strict guidelines for mattresses in terms of chemical additives these days and many of the chemicals used in the past (such as Flame Retardant sprays) are no longer used on any mattresses.
  • Memory Foam: Memory foam has recently become very popular in the bedding market. The material was originally made for use by NASA and was ultimately used in mattresses due to its unique pressure relief and cradling properties. Memory foam has a very unique feel that some people love and others hate. If you have never tried sleeping on a memory foam mattress before it is important to note that the feeling it very different from a traditional spring mattress.

How much does a split California king mattress cost?

In general a set of 2 split California kings mattress halves will cost slightly more than a single California king due to the increased material and labor it takes to make two separate mattresses. This price difference, however, is very small. It is important to note that the majority of companies listed sell their split mattresses and halves and you will need to purchase 2 units in order to complete the bed. Expect to pay anywhere from $300-$1500 per half depending on the quality of mattress and materials you choose. For the most part, memory foam will be the most affordable material while latex foam will be the most expensive. 

Things to consider before choosing a split California king mattress.

There are a variety of split king mattresses on the market and it is important to think about your specific needs when choosing which may be best.

  • Usage: How often will you be sleeping on this mattress? How long will it need to last? If you plan to sleep on this mattress for multiple nights in a row or want it to last for many years we recommend staying away from the entry level affordable mattresses. These entry level mattresses are intended for occasional use and won’t hold up as well as some of the higher end mattresses.
  • Material: Do you prefer a specific type of feel. The comfort level of Memory foam to innerspring mattresses or latex mattresses is all very different. It is important to understand what it is you like to sleep on before choosing a mattress that is right for you.
  • Firmness: What firmness do you prefer? Many of the mattresses we provide on this list will allow you to choose a firmness or are built to accommodate the large 80% of sleepers who prefer to sleep on a medium-firm mattress.
  • Customization: Do you have 2 sleepers with different comfort preferences? If this is the case then you will want to choose a mattress that is sold as 2 separate units. This way you can choose a different firmness or style for each mattress.
