That means avoiding sheets labeled “wrinkle-free,” “easy care,” or “permanent press,” since they were likely treated with formaldehyde resin—a known carcinogen. Instead, look for 100 percent organic options, especially if you’re going the cotton route since cotton only covers 2.4 percent of the world’s farmland, but it accounts for 24 percent of the global sales of insecticide and 11 percent of pesticides sales. But don’t take claims at face value: Even if a company says its fabric is organic, the claim doesn’t hold much weight unless it’s backed up by a trustworthy label. Oeko-Tex Standard 100 Greenguard Gold and Global Organic Textile Standard (GOTS) labels are the most trustworthy ones for fabric, according to a recent study by Consumer Reports.
