The difference between a king (sometimes also called a divided king or horizontal king) and a split king can be confusing. Each type is available in Split Cal King and Cal King, as well. We're here to tell you what makes each adjustable base different. That way you can understand your options better.
If you'll consider the images below you'll notice an obvious difference between the two types of power bases. The divided king separates in the middle of the bed from side to side. The split king divides down the middle from head to foot. This isn't the only difference, just the most obvious one. There are more that define the uniqueness of each adjustable foundation, read on for more details.
|Designed for King size mattresses specifically, but can work with two Twin XL mattresses as well||Designed for either two separate Twin XL mattresses or one King|
|Two motors operate the base, one for the head portion, one for the foot portion||Four motors, two for the head and two for the foot portion that can work independently or be paired together|
|The head and foot portion arrive in their own boxes but the two pieces make one whole adjustable foundation||The two pieces are each one individual base|
|The lifting function for either the head or foot lift the entire section||Each side can work independently of one another|
|The two pieces cannot work independently of one another||You can get two different comfort types in two Twin XL mattresses to cater to each person's comfort preference|
Which option you choose really comes down to two questions. 1. Is your King size mattress made up of one King size mattress or two Twin XL mattresses? If your answer to this question is “1 king size mattress” then the choice for you is fairly easy. While it is possible to use a split king base with a king mattress, all the extra functionality of a split king base will go unused because of the single-piece mattress. So why not go with the king base to save yourself a little money. If your answer to this question was “two Twin XL mattresses” then ask yourself this next question. 2. It is possible my partner would prefer to be in a different adjustable position than I would? If you answered “yes” then the split king adjustable base would be a better choice for you. If you answered “no” then the king base is likely the best choice for you.
