Frequently asked questions

Yes, split king sheets consist of two fitted sheets for each side of a split king bed, but the flat sheet and pillowcases are shared. Some sets are sold as twin XL separately.
How do I care for Egyptian cotton sheets?
Wash in cold water on gentle cycle, tumble dry low, and remove promptly to reduce wrinkles. Avoid bleach and high heat to preserve fibers.
What certifications should I look for?
OEKO-TEX Standard 100 ensures no harmful substances. GOTS certification indicates organic cotton. Look for both for quality assurance.
