Frequently asked questions
What is the best sheet material for a 16-inch mattress?
The best material depends on your preference. Percale cotton offers crisp breathability, sateen is silky, microfiber is budget-friendly, and bamboo lyocell provides cooling. Ensure the pockets are at least 16-18 inches deep.
How deep should pockets be for a 16-inch mattress?
Pockets should be at least 16 inches, but 17-18 inches is recommended to account for mattress toppers or variations in mattress height. Always check the product specs for pocket depth.
What certifications should I look for in sheets?
Look for OEKO-TEX Standard 100 certification for no harmful chemicals, and GOTS for organic materials. CertiPUR-US may apply to foam layers if present, but for sheets, OEKO-TEX and GOTS are key.
Can I use regular deep pocket sheets on a 16-inch mattress?
Most 'deep pocket' sheets fit mattresses up to 15-16 inches. For a true 16-inch mattress, choose sheets labeled with a pocket depth of 16 inches or more, or 'extra deep pocket' up to 18 inches.
How do I keep sheets from slipping off a thick mattress?
Look for sheets with elastic all around the hem (not just corners), deep pockets of at least 17 inches, and corner straps. Sheet suspenders or clips can also help secure them.
