Not every couple can agree on the perfect mattress specifications. Some like it firm, while others prefer a soft, pillowy surface. There’s no need to compromise when you opt for a split king mattress. This consists of two twin XL mattresses that are typically joined with a special midsection connector.

Finding the proper sheets for your split king can be a bit difficult, though, since it’s not a standard mattress size. And not every retailer sells split king sheets. This article will help you find the right sheets for your slumber.

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.

Here’s how we narrowed down our list of the best split king sheets:

  • Size. We made sure only to include sheet sets designed explicitly for split king mattresses, so this list is free of twin XL sheets. We also included various options, from deep pocket sheets to options made for adjustable beds.
  • Materials. The list includes sheets in a variety of materials to fit different preferences. You’ll find options like cotton, bamboo, sateen, and more.
  • Customer reviews. The customer is always right—and we take customer feedback seriously. That’s why we only feature products that get rave reviews from users. And if there’s a downside, we make sure to mention it so you’re fully informed.

When shopping for split king sheets, here’s what’s most important to keep in mind.

  • Your mattress. Not all split king mattresses have the same specifications. Extra-deep mattresses may require a deep pocket sheet set. And if you have a split head king, you’ll want a split head sheet set, not a split king set.
  • Your sleep temperature. Hot sleepers should opt for breathable fabrics like bamboo. If you get cold at night, flannel might be more your speed. And it’s not just for the sake of comfort. Research from 2017 shows that your sleeping temperature can affect your sleep quality.
  • OEKO-TEX certification. This certification is a good quality indicator and ensures that your comfy sheets are free of unwanted chemicals.

Who are split king sheets right for?

You’ll need split king sheets if you have a split king mattress. And if you have a split head king, you’ll need split head king sheets for your bed.

Is a split king mattress the same size as a king?

No. A split king mattress is two twin XL mattresses pushed together with a connector in the middle. A king mattress has no middle part, and there’s no way to customize each side.

What sheets do you buy for adjustable beds?

Sheets for adjustable beds will usually have corner elastics for an extra secure fit. Additionally, if you have a split head bed, you’ll need sheets designed specifically for this purpose.

Getting the right sheets for a split king is essential. If you opt for a king-size fitted sheet for a split king, you’ll likely end up slipping and sliding throughout the night.

The perfect split king sheets will depend on whether you sleep hot or cold, what kind of feel you’re looking for, and the depth of your mattress.
