Frequently asked questions
What size is considered extra large for bed sheets?
Extra large typically refers to fitted sheets that fit mattresses over 12 inches thick. Some brands offer 'deep pocket' sheets for 15-18 inch mattresses, and 'extra deep' for up to 24 inches.
Are bamboo sheets better than cotton for extra large beds?
Bamboo sheets are often softer and more breathable, but cotton percale is more durable. For extra large mattresses, look for deep pockets regardless of material.
How do I ensure a good fit for my thick mattress?
Measure your mattress height and look for sheets that specify pocket depth at least 2 inches greater. All-around elastic also helps secure the fit.
What certifications should I look for in extra large sheets?
OEKO-TEX Standard 100 ensures no harmful chemicals. CertiPUR-US is for foam, but for sheets, OEKO-TEX is key. GOTS for organic cotton.
Do extra large sheet sets include more than two pillowcases?
Some sets include four pillowcases, like the Lucid 6-Piece. Always check product description for what's included.
