How to choose a fitted sheet for an adjustable bed
Adjustable beds require fitted sheets with deep pockets and stretch. A standard sheet may pop off when the head or foot raises. Look for a pocket depth that exceeds your mattress height by at least two inches. Elastic all around the hem helps keep the sheet snug. Fabric with spandex or a knit weave offers more give. Microfiber is a common choice because it stretches and resists wrinkles. Cotton sateen also works but may be less elastic.
Understanding sheet materials: microfiber vs cotton
Microfiber is a synthetic fabric made from finely woven polyester. It is soft, durable, and often cheaper than cotton. However, it can trap body heat and may not breathe as well. Cotton is natural, breathable, and gets softer with washing. But cotton sheets may wrinkle and shrink. For adjustable beds, microfiber's stretch is an advantage. If you sleep cool, consider a cotton blend with some spandex. Always check the care instructions to maintain fit and feel.

Questions before you buy
Does the Mellanni king fitted sheet fit a 16-inch mattress?
Yes, the pocket depth is up to 16 inches, so it fits mattresses up to that height. Some owners say it fits thicker mattresses with a topper, but it may be snug.
Is this sheet suitable for a split king adjustable bed?
No, this is a regular king size, not split. For a split king, you need two twin XL fitted sheets. Mellanni offers separate twin XL sizes.
Can I use this sheet without a top sheet?
Absolutely. Many buyers use it alone with a duvet or comforter. The fitted sheet is sold individually, so you can pair it with any top bedding.
How does the Mellanni sheet feel compared to cotton?
Microfiber feels smoother and silkier than cotton, but it is less breathable. Some users describe it as soft and cozy, while others find it too warm.
Will the sheet stay on during adjustable bed movement?
Owners report that the deep pockets and elastic keep it secure. The stretchy fabric moves with the bed. However, if the bed is raised fully, the sheet may shift slightly.
What is the thread count of this sheet?
Thread count is not listed because microfiber is measured differently. The fabric is 100% polyester microfiber, which is known for its softness and durability.
Can I put this sheet in the dryer?
Yes, it is safe to tumble dry on low. High heat may damage the elastic or cause shrinkage. Remove promptly to reduce wrinkles.
Is the Mellanni sheet wrinkle-free?
It resists wrinkles well, especially compared to cotton. Some wrinkles may appear after washing, but they smooth out quickly.
