2021’s Best Cotton Sheets for a Perfect Sleep

Shopping for suitable bed sheets can be challenging.

You’ve sifted through tons of fabric and settled for good old cotton. You’re sure you’ve nailed it because cotton sheets are comfortable, breathable, and durable.

But there’s more to consider.

The cotton used, how it’s woven, and the thread count will determine how exceptional your cotton sheets are.

We’ve done the groundwork for you. We’ll give you helpful pointers on choosing the best cotton sheets and present our top picks to make shopping easier for you.

Here’s a sneak peek of our favorite cotton bed sheets.

How to Choose Quality Cotton Sheets

Types of Cotton

The type of cotton used determines the staple length and quality of your sheets. The longer the staples, the finer the sheets. 

  • Egyptian cotton — Has long staples that make luxurious and durable sheets.
  • Pima cotton — With extra-long staples, Pima cotton sheets are as premium as
    Egyptian cotton sheets.
  • American Upland — The most common short staple cotton. It grows quicker than premium cotton and is cheaper to process and weave. Consequently, Upland cotton fabric is cheaper and of lower quality.

Type of Weave

The type of weave will influence how crisp and cool or heavy and warm your sheets are. 

  • Percale — Woven in a tight crisscross pattern, one yarn over another. The simple style makes the fabric lightweight and crisp, which ensures you sleep cool.
  • Sateen — Woven in an irregular pattern to give you silky, lustrous sheets with a smooth drape. The sheets are heavier and warmer, making them ideal for cold weather.

Thread Count

You’ve probably heard the higher the thread count (the number of vertical and horizontal threads per square inch of fabric), the softer the sheets. However, this is not always the case.

Sheets with a low thread count are very thin, but high thread count sheets can be rough and scratchy. Your best bet is to look for an average thread count between 200-600.

Let’s dive into the nitty-gritty of our top cotton sheets.

The Brooklinen Luxe Core Sheet Set hits the mark with everything you need from cotton sheets — soft, comfy, durable, and breathable.

The sheets are made with a sateen weave from pure long-staple cotton, making them ultra-soft with a lustrous finish. In addition, a 480 thread count ensures durability. In fact, your sheets get softer with every wash.

The Luxe Core sheets are ideal for:

  • Allergy-prone sleepers, as they are OEKO-TEK certified (no harmful chemicals)
  • Cold sleepers as sateen weave is heavier and warmer

If you sleep hot, you risk waking up clammy and will sleep better on lightweight cotton percale sheets like the Casper Cool Supima sheets.

You’re sure to find a sheet set you’ll love as they come in:

  • All standard sizes — Twin, Twin XL, Full, Queen, King, and Cal. King
  • A variety of colors and patterns
  • A four-set bundle including a 15 inch deep fitted sheet, one flat sheet, and two pillowcases

Note: you can buy individual pieces or mix and match sheet sizes.

If you’re still not sold and need to sleep on the sheets to believe, Brooklinen offers samples and a generous 365 day trial period. And if you keep them, you get a lifetime warranty.
