What are split king sheets?
Split king sheets are designed to fit a split king mattress, which is two twin XL mattresses squished together. This type of mattress is excellent for couples who want to customize their sleep experience. You can also use a split king mattress with an adjustable bed frame.
While you could just buy two twin XL sheet sets, a split king sheet set helps you create a cohesive look and cozy feel. It typically includes two twin XL fitted sheets, a large, king-size flat sheet, and matching pillowcases.
Split king sheets are also available for adjustable beds. These mattresses allow you to raise or lower the head or foot of the bed to your liking. Adjustable split king sheets feature straps to keep them in place even as you adjust the angle of the mattress. They may also have deeper pockets.
