Why split king sheets need special attention
A split king mattress is two twin XL mattresses side by side. Each side moves independently on an adjustable base. Standard king sheets are too wide and will bunch or tear. Split king sheets come with separate fitted sheets for each side. This design allows each side to move without pulling the other. The Southshore set addresses this with two fitted sheets and two flat sheets, so each side gets its own bedding.
How to ensure a good fit on adjustable beds
Measure your mattress depth before buying. The Southshore set fits up to 18 inches, which covers most adjustable mattresses. Check that the elastic goes all the way around the fitted sheet. Full elastic perimeter helps the sheet stay anchored when the head or foot raises. Look for deep pockets that can accommodate pillow-top mattresses. The set's elastic is reinforced at the corners, which owners say prevents slipping.

Questions before you buy
What is a split king sheet set?
A split king sheet set includes two twin XL fitted sheets and two twin XL flat sheets, plus pillowcases. It is designed for split king mattresses, which are two twin XL beds placed together. Each side has its own fitted sheet so it can move independently on an adjustable base.
Will these sheets fit a regular king mattress?
No. The split king set is specifically sized for two twin XL mattresses. A regular king mattress is one piece, so you would need a standard king sheet set. Using split king sheets on a regular king would leave gaps and not fit properly.
How deep are the pockets on the Southshore split king sheets?
The fitted sheets have deep pockets that accommodate mattresses up to 18 inches thick. This includes most adjustable mattresses and those with pillow tops. The elastic all around helps keep the sheet secure on thicker mattresses.
Are these sheets soft?
The sheets are made of microfiber, which is known for a soft, smooth feel. Many owners describe them as comfortable and breathable. However, some prefer the crispness of cotton. Microfiber is also wrinkle-resistant, which is a plus for easy care.
Can I use these sheets on a non-adjustable split king bed?
Yes. The sheets work on any split king mattress, whether it is adjustable or not. The separate fitted sheets are useful for any split king configuration. They also make it easier to change one side without disturbing the other.
How do I wash and care for these sheets?
Machine wash in cold water with similar colors. Use a gentle cycle to reduce wear. Tumble dry on low heat and remove promptly to minimize wrinkles. Avoid bleach and high heat, which can damage the microfiber fabric.
Do the sheets stay in place when the bed is adjusted?
Owners report that the full elastic perimeter helps the fitted sheets stay put, even when the head or foot is raised. The deep pockets also prevent the sheets from popping off. Some users still need to tuck the flat sheet, but the fitted sheets generally stay secure.
Is the Southshore split king set worth the price?
Given the included pieces and the secure fit, many owners find it a good value. It is not the cheapest option, but it offers durability and performance. If you need a reliable split king set, the price is reasonable compared to similar products.
