The Ideal Fit for Adjustable Comfort

Split King beds require a unique sheet solution, and our fitted sheets deliver with precision. Each set includes two Twin XL fitted sheets that stay securely in place, even as your bed moves. Our long-staple cotton is hand-harvested and woven in a signature 4-over-1-under pattern, which allows the fabric to become softer over time without relying on synthetic softeners or chemical treatments.

These sheets are a part of a bedding collection built on trust, transparency, and ethical craftsmanship. From the planted seed to the final stitch, every step of the process is traceable, sustainable, and held to the highest standards.

If you're setting up a new adjustable bed or upgrading from conventional cotton sheets to something with a more luxurious hand feel, our Split King Fitted Sheets are a choice you’ll feel good about each time you close your eyes.
