Why split sheets matter for adjustable beds
Standard fitted sheets pop off when the bed bends. Split sheets have two separate fitted halves. Each half moves with its side of the bed. This prevents wrinkles and bunching. The Mellanni set uses this design. It keeps the mattress covered even at full incline.
How deep pockets affect fit
Deep pockets are essential for thick mattresses. Mellanni's pockets fit up to 16 inches. That covers most pillow-top and foam mattresses. The elastic goes all around the hem. Owners say the sheets stay put without slipping. Measure your mattress depth before buying. If yours is thicker than 16 inches, look elsewhere.
Fabric feel and maintenance
Brushed microfiber is soft and wrinkle-resistant. It is also lightweight and easy to wash. The set dries quickly. However, microfiber is synthetic. It may not breathe as well as cotton. Some users find it warm. Follow the care label to avoid pilling. Use cold water and low heat.

Questions before you buy
Do these sheets fit a split king adjustable bed?
Yes, the set includes two twin XL fitted sheets that fit each half of a split king. The flat sheet is one piece, so it covers both halves.
What is the maximum mattress depth?
The extra deep pockets fit mattresses up to 16 inches thick. Check your mattress height to ensure a snug fit.
Are these sheets soft?
Many owners say they are soft and get softer after washing. The brushed microfiber has a smooth, cozy feel.
Can I use these sheets on a regular king bed?
No, the fitted sheets are split, so they are designed for split king beds. For a standard king, consider the regular king version.
Do the sheets stay on when the bed is raised?
Owners report that the split design and deep pockets keep the sheets in place, even when the head or foot is elevated.
How do I wash these sheets?
Machine wash in cold water and tumble dry on low. Avoid high heat to prevent shrinkage and pilling.
Are these sheets breathable?
Microfiber is less breathable than cotton. Hot sleepers might find them warm, but they are fine for cooler climates.

The split king set includes one flat sheet, two fitted sheets, and two pillowcases.
