Frequently asked questions
What is considered a deep mattress?
A deep mattress typically measures 12 to 18 inches thick, though some go up to 24 inches. Deep pocket sheets are designed to fit these mattresses securely, with pocket depths ranging from 15 to 24 inches.
How do I measure my mattress depth for sheets?
Measure from the bottom of the mattress (where it meets the box spring or foundation) to the top of the mattress. Add an extra 2-3 inches to ensure the sheet covers the full depth and tucks under securely.
Are fitted sheets for deep mattresses different from regular ones?
Yes, deep pocket sheets have larger pockets and stronger elastic to accommodate thicker mattresses. Regular sheets may pop off or not fit at all on deep mattresses.
What certifications should I look for in deep sheets?
Look for CertiPUR-US (foam safety) and OEKO-TEX Standard 100 (textile safety). These ensure the sheets are free from harmful chemicals and meet environmental standards.
What is the best fabric for deep pocket sheets?
Cotton (especially percale or sateen) is breathable and durable. Bamboo viscose offers cooling properties. Microfiber is budget-friendly but less breathable. Choose based on your temperature needs and budget.

Our overall winner is the Brooklyn Bedding Deep Pocket Sheet Set, offering a secure fit and soft feel for mattresses up to 18 inches.
