Frequently asked questions

Measure your mattress height including any topper. For mattresses 10-15 inches, look for 15-inch pockets. For 16-22 inches, choose 18-21 inch pockets. Our top pick fits up to 21 inches.
What materials are best for deep fitted sheets?
Microfiber is affordable and wrinkle-resistant. Bamboo (viscose) offers cooling and softness. Cotton percale is crisp and durable. Choose based on your temperature preference and budget.
Will deep fitted sheets work on adjustable beds?
Many deep sheets with strong all-around elastic work well on adjustable bases. Look for sheets with extra elastic and stretchy fabric, like the Nestl Deep Pocket Bamboo Sheets.
How do I keep deep sheets from popping off?
Opt for sheets with elastic all around (not just corners) and a pocket depth that exceeds your mattress height. Sheet straps can also help secure the fit.
Should I look for certifications?
OEKO-TEX certification ensures the sheets are free from harmful substances, which is important for sensitive skin. CertiPUR-US applies to foam, not sheets. Look for OEKO-TEX for peace of mind.
