Split King Bed Size

However, unlike a king bed that is made up of a single mattress, a split king is made up of 2 separate single mattresses, and the configuration is popular for adjustable bed frames. This allows couples to maintain their own controls (Reclining and Inclining, Massage Settings, and much more) on their side of the bed.
