What is a Split California King?

Choosing the perfect mattress can be a complex journey. Amongst the plethora of options available, the Split California King emerges as a luxurious choice for those looking for customizable comfort. Let’s delve into the world of Split California King mattresses and understand what sets them apart.

What is a Split California King Mattress?

The Split California King, a luxurious variant of the regular California King, offers a tailored sleep experience for couples. It comprises two separate mattresses, each tailored to the individual’s preference, allowing for customized firmness levels.

This ensures both partners can have their desired comfort without compromising. If one of you prefers a firm surface while the other enjoys the plush comfort, the Split California King delivers just that.

Split California King Dimensions

Understanding the size is crucial when considering this mattress:

  • Width: 72 inches (split into two 36-inch mattresses)
  • Length: 84 inches
  • Ideal for: Couples with distinct firmness preferences, adjustable beds.

Given its split nature, it offers flexibility, especially for adjustable bed frames like the Puffy Adjustable Base in Spli King size where each side can be adjusted independently.

Is a Split California King Two Twin XL?

A common misconception is equating a Split California King with two Twin XL mattresses. Here’s the clarification:

  • Twin XL Dimensions: 38 inches by 80 inches
  • Split California King: 36 inches by 84 inches (each half)

While they might seem similar, the Split California King is narrower but longer than the Twin XL. So, for those considering merging two Twin XLs to replicate a Split California King, it wouldn’t be an exact fit.

California King Split Box Spring Size

For those looking to complete their bed setup, understanding the box spring size is crucial:

  • Width: Typically split into two 36-inch box springs
  • Length: 84 inches

The split design ensures easier maneuverability, especially in homes with tight corners or stairways.
