We often get the question: What is the difference between a split king adjustable bed and a king-size bed, and is a single king mattress compatible with split bases? In this article, we will explain in depth the differences, setup, and cost between the two sizes.

What are the Different Sizes Between the Two Sizes?
There are two sizes of King-size adjustable beds. A single king-size measures 76 inches by 80 inches, and a split king with two bases measures 38 inches by 80 inches. The main difference is that the split king can be used with split king mattresses to move independently or a king mattress by syncing both sides together, while a king size can only have a single king mattress.
What is the Cost Difference between Both King Sizes?
Typically, split king adjustable beds will cost more than the single king bases. This is because having two of everything. For example, extra motors for each side of the base, two power cords, and a power box. This is the main reason why the split king bases are more expensive than the standard king base.
How to Choose Between Split King or King Bases?
The main thing to choose from is who will sleep in bed. Many couples want split bases to have different adjustments on each side, and there are others that are ok with only having one control for the whole base. One thing to consider is whether one is ok with the line down the middle or whether one is ok with the whole base moving altogether. This is the biggest factor when choosing between the two different base sizes.
