SPLIT CALIFORNIA KING MATTRESS BUYER'S GUIDE

What is a Split California King Mattress?

There are a few things to know about a Split California King Mattress.  First, the size of the sleeping surface is divided into two, separate mattresses.  Each is 36” wide and 84” long, with a combined total sleep surface of 72”x84” when set side by side.  The second thing to know is that a Split California King Mattress is sometimes referred to as a “Western King.”  It is called this due to its roots in the West Coast.  As the size became more popular, especially with taller consumers, it shifted to being named Split California King.

Now one of the greatest benefits of a Split California King mattress is that it can be partnered with an adjustable bed.  A single mattress used with a Split California King adjustable bed is great, but a split mattress increases the functionality.  Each side then has its own, individual adjustability unhindered and unaffected by the other side.

WHY YOU SHOULD BUY

Many adjustable beds do come in a size to fit a Split California King mattress.  A Split California King adjustable bed must come as two bases which measure 36”x84” in order to match.  Some adjustable bed brands are becoming less available in this size, moving towards single California King instead.  However, there are still several options accessible.

How to Measure the Total Height of the Mattress with the Base?

It would help if you considered some sets when measuring the overall height of the mattress with the base. Knowing the height is very important since shorter people may want to avoid having taller mattresses, whereas taller people would like a tall overall mattress height. Some of the steps that you will take when measuring the total height of the mattress with base include:

  • First: The first step is to measure the overall foundation height. The foundation can be a box spring with a simple metal frame or an adjustable bed.
  • Second: The second step is to measure the overall height of the mattress. Usually, the height of the bed ranges from 10 inches to 13 inches tall.
  • Third: The third step requires you to add up all measurements of the mattress and the foundation’s total height to get the bed’s total height.

 

Split California King Vs California King Mattress

The likeness between a Split California King and the traditional California King lies in the total length and width. Both options provide 84 inches of length for tall sleepers to stretch out. Both are also 72” wide from one side of the complete bed surface to the other. The Split California King mattress is basically two mattresses with dimensions of 36”x84” each. Both sizes can be used with an adjustable bed, but there is a key difference in how the mattress allows the adjustable bed to operate. With a single California King, the bed is controlled as one single bed no matter what. With the split variety, a sync cord determines how it works. If the cord is in use, the two sides will run the same as if the mattress being used is a single mattress. If the bed is not being synced, each side of the bed will have the ability to move about positions in separate fashion.

Split Western King Mattress (2) With A Dimension of 36 Inches by 80 Inches

A standard Western king mattress measures 72 inches by 84 inches. However, a split western king mattress measures 36 inches by 84 inches. The split California king mattress was created by the man known as David Bergeson. David Bergeson was from Concord, CA. The reason why David Bergeson created the Western king mattress is because his legs were too long to fit a traditional king-size mattress. David designed the split western king mattress for the people who were living in California, but later, the California king bed size was introduced to pair with the split California king adjustable bed, which some individuals may call an adjustable bed. The split western bed was initially designed for people who required longer beds. Also, the mattress was split into two sections to allow the individual on each side to adjust to the comfort level based on their preferences.

 

Split California King vs Split King


King size and Split King are two other similar mattress sizes. The King is wider at 76” but shorter coming in at 80” long. A Split King, just like the Split California King mattress, comes in two pieces. Its sides are 38” wide but only 80” in length. While the King sizes are more common, California King is gaining popularity. At the end of the day, the longer bed is going to likely be more comfortable for tall users.

 

Different Types of Split California King Mattresses

There are different types of split California king mattresses. These types include hybrid, latex, and gel memory foam. Currently, there are no innerspring or air-split California king mattresses.

rest right mattress split california king mattress latex

  • Latex Mattress

Latex mattresses are made from natural materials extracted from rubber trees. They are restful natural products made in three layers with different firmness. Latex mattresses are well-known for their durability, hypoallergenic characteristics, and breathability. They provide a buoyant feel, conforming to the body without sinking too much. If you prefer a natural product, a latex mattress would be the best.

 

  • Memory Foam Mattress

Memory foam mattresses are available in split California king mattresses. They are made from viscoelastic foam that conforms to the shape of the body, providing personalized support, comfort, and reduced pressure.

  • Hybrid Mattress

A hybrid mattress has independent coils. It can be latex and coils or memory foam and coils. The Kingship comfort hybrid is made of latex and coils. Hybrid mattresses provide a good balance of support, pressure relief, and motion isolation.

  • Air Mattress

There are no air mattresses in split California king-size. The only air mattress that is available is a split-top California king air mattress that can fit with split-top California adjustable beds. However, the adjustable bed for the split-top cannot have a wall hugger.

rest right mattress split california king mattress memory foam

  • Gel Memory Foam

Gel memory foam mattresses have gel beads or gel-infused foam within their memory foam layers, which have cooling properties and regulate the temperature. Gel memory foam provides the contouring support of the additional memory foam, which also has the benefit of cooling. Since memory foam retains heat, the gel makes the mattress cooler at night.

 

  • Innerspring

There are no innerspring split California king mattresses available. This is because split mattresses are made to work with adjustable beds and innerspring mattresses are made with wires that connect the coils. The wires do not allow the mattress to bend for an adjustable bed.

 

How to Choose A Split California King Mattress?

  • Mattress Type: As you can see, there are several types of mattresses available in the Split California King size.  These mattresses come in memory foam, latex and hybrid.  They can be a set firmness, or have adjustable firmness capability.  Pinpointing which materials you prefer will help to narrow down the options.
  • Price: Price is also a very dominant factor affecting which mattress one chooses.  The higher end Split California King mattresses are going to be latex or hybrid mattresses.  Memory foam mattresses tend to be most economical as the material to build them costs less.\
  • Mattress Height or Thickness: How thick of a mattress is needed is something else to consider as it affects the overall height of the bed.  When deciding on this, just remember that pairing it with an adjustable bed or custom bedframe will impact the decision.  Standard box springs run about 15 inches and adjustable beds may have a base profile similar to that or offer adjustable legs.
  • Warranty: There is a 15-year limited manufacturer’s warranty on the Kingship Comfort line of mattresses.  This includes the Kingship Comfort Restful Latex mattress as well as the Kingship Comfort Superior, Hybrid and Classic Series.
  • Country in Which the Mattress is Made: All the Kingship Comfort mattresses are made and sourced in the USA with one exception. Latex trees must grow in a tropical environment, so the Kingship Comfort Restful Latex Mattress is made in the USA from imported material.
  • Are There Any Sales on Split California King Mattresses? Usually, there are combo sales on both mattress and adjustable beds for Split California King.
  • What is the Cost of a Split California King Mattress? The cost of one side of the split California king mattress can be under $1000.00, but if one buys a set of split California king mattresses, the price will range from $1050.00 up to $1840.00.
  • Watch the Name of Split California King Size: The name of the California king-size is just for one side of a split California king-size mattress set. But on our site, we name split California king mattress for two pieces, which includes both sides; this means that both sides are together at that price.

 

Split California King: Personal Factors to Consider

Before choosing the mattress you will buy, there are personal factors that you should consider. These factors include health considerations, sleeping positions, sleep time, body weight, and height.

rest right mattress split california king mattress body weight and height

  • Body Weight

The body factor is an important factor to consider because the mattress can be too soft or too firm based on the body’s weight. Dr. John P. Cunha suggests that individuals who are 6’3″ in weight should be in the range of 152 lbs to 192 lbs. Individuals with this weight require a mattress with medium comfort, which will be preferred by back, side, or combination sleepers up to 260 lbs.

 

  • Sleep Time

The amount of time you sleep will account for how long you will be using the mattress. Guessing the type of mattress is not as important as sleeping on it every night. Sleeping on a quality mattress every night is important to an individual’s overall health.

rest right mattress split california king mattress sleeping position

  • Sleeping Positions

When choosing a mattress, consider the sleeping position. Side and back sleepers usually prefer a medium-comfort mattress, while stomach sleepers prefer a firmer mattress.

 

  • Height

When buying a mattress, height is an essential factor to consider. In the United States, male height has increased by 6 cm over the past 150 years. Since individuals are getting taller, the demand for longer mattresses, such as California King, is high. If you don’t fit on a 36 inches by 84 inches mattress, then you will choose the split Wyoming king mattress, which measures 42 inches by 84 inches.

 

How to Change the Height of the Mattress?

The overall height of the mattress is essential to some customers. This is because many mattresses are set in height. When you pair the split California king mattress with the adjustable beds, many adjustable beds have adjustable legs, which can be adjusted to change the overall height of the mattress. For instance, the mattress is 12 inches, and the standard height of the legs of the adjustable bed from the ground to the top of the base is 15 inches. If an adjustable bed model has adjustable legs, which allows the base of the bed to be lowered, for example, 13 inches, and the height of the mattress is still 12 inches. The overall height would be 25 inches compared to the total 27 inches.

 

How Does the Split California King Mattress Ship?

The Split California King mattress is shipped through FedEx. The mattress is compacted in a box for convenient transport inside and into the bedroom. You will receive a tracking number through email in 6 business days, Monday through Friday. The mattress will not be delivered to your residence but instead in a box curbside or where FedEx regularly delivers to you.

 

Where to Buy Split California King Sheet Sets?

As the size of Split California King sheet sets are not standard, many brick and mortar retailers don’t carry them.  Therefore, these are usually purchased online. One company, called Sleep and Beyond, makes organic Split California King Sheets.  These stand out because they are 100 percent organic and they are certified organic bedsheets.  They have a sateen weave and a 300 treadcount.

 

Our Thoughts On Split California King Mattresses

Based on our experience and customer feedback, we believe that a split California king mattress is more suitable for taller people and those that use a California king-size mattress but want a split instead. However, each customer is a little different. When it comes to which type of split California king mattress to choose, the customer should decide based on their own personal preferences. One such preference is the comfort level the user wants. This comfort level is selected according to how the user sleeps, on their side, back, stomach, or combination. Many customers prefer a medium comfort level because it caters to users who sleep on their back and side or combination sleepers. On the other hand, users who sleep on their stomachs prefer a firm mattress.
