I’ve spent about a decade testing sheets at Wirecutter, which sounds like an odd way to spend a career. Sheets are one of those life basics that seem so simple, they’re hardly worth obsessing over. Do they fit on the bed? Do they feel good? What else is there?Oh, but believe me, I obsess over them. You spend so much time nestled between bedsheets that it’s actually one of the most intimate relationships in your life. They carry sense memories, and feelings of comfort and home, too. They’re with you when you’re sick, they’re with you when you’re tired, and they’re with you when you’re up to something that might involve putting a little Marvin Gaye on in the background.And cotton sheets are the most basic of basics. You might dabble in linen or treat yourself to flannel, but cotton sheets — the percales and the sateens — are the most common and versatile sheets you buy.In this guide we’ve included the 10 best sheets we’ve tested over the years: Some are reliable classics we’ve loved for a long time, while others have impressed us more recently, but all of them have earned their keep in our book. With a selection ranging rom a rainbow of solids to modern prints, at prices from around $50 to well over $2,000, you’re bound to find something you’ll love here. I’m sure I haven’t covered everything yet — but give me another decade, and I’ll get there.
