Many of us grew up snoozing on cotton pillowcases — but it turns out silk pillowcases are way better when it comes to beauty sleep. Unlike the cotton variety, silk pillowcases can reduce friction on skin and hair — and with it, frizzy bedhead and those weird morning creases in our faces.

We spend (in theory) one-third of our lives against our pillows, so making this swap is one way to instantly upgrade not only our beds, but our lives. Plus, silk is nice and cooling, and just feels so darn luxurious. But silk pillowcases can be pricey, so you want to be sure you’re buying ones that are a great value. And that’s where we’re jumping in.

What to look for in a silk pillowcase

First off: It’s really easy to mix up satin and silk.

Silk is a natural fiber and satin is a weave (the method by which fibers are made into a fabric). Satin fabric can be woven with different kinds of fibers, such as rayon, polyester, nylon and silk blends. Silk is just, well, silk. Silk costs more than satin, since it’s harder to produce (you know, wrangling silkworms and all).

The fabric weight of silk is expressed as momme, or mm (the equivalent of thread count with cotton bedding.) You’ll see pillowcases that range from 15 to 30 momme, with 19 about typical. Mulberry, produced by silkworms fed on mulberry leaves, is the highest quality silk, with the longest and most uniform fibers, so the fabric is uber smooth and durable.

Silk is also naturally hypoallergenic. After all, it’s a substance that evolved to protect growing silkworms, and so is known to be resistant to mold, mildew, fungus and mites.

Even understanding all that, wading through the many (and we mean many) silk pillowcases on Amazon can be a bit maddening. Yes, they do all look pretty much alike. So we combed through countless comments from the most enthusiastic reviewers on Amazon to uncover the top silk pillowcase picks, all of which have at least a 4-star rating and hundreds (if not thousands) of reviews. To make comparison straightforward, all prices are for one queen-size pillowcase, unless otherwise noted. Consider your silk pillowcase shopping sorted.
