Silk sheets are expensive, so you want to make sure you're investing in ones that are actually worth the splurge. Here’s what to look for in silk sheets:

• Quality. For each product, we looked at the metric called “momme,” which is a Japanese word for weight measurement in silk. It’s similar to a thread count but specific to silk. In general, the higher the momme, the denser the fabric. Silk sheets can fall anywhere between 12 and 30 momme. Silk is also graded on a letter scale for quality (from A to C), so we also included that information where we could.

• Transparency and certifications. Brands should be straightforward and clear about how their products are made. Most of the sheet sets on this list received OEKO-TEX Standard 100 certification, meaning that they were tested and are free of harmful chemicals, even beyond international requirements.

• Style. Most options on this list offer a variety of sizes and colors to help you determine what fits your style.

• Customer reviews. We cross-referenced websites, articles, and review videos to ensure we selected products that reflected the best of what the silk sheet market has to offer.

Silk sheets are pricey, but you get what you pay for. Invest in a mulberry silk sheet set that is at least 19 mm, and you'll have some durable, beautiful, super-soft bedding on your hands and under your head.
