Getting the best king flat sheet can make or break how comfortable you feel in bed. A good flat sheet should fit properly and tuck neatly in place while also allowing you to add a duvet or comforter over the top of it.

To find the right king flat sheet for your bed, start by removing any existing sheets and measuring your mattress height, width, and length. Then note down those dimensions and any mattress topper you may have. That way, you can match the exact measurements of your new sheets to your mattress.

Luxe and Generous: Discovering the Perfect King Flat Sheets for Your Bed

A king mattress measures 76 inches wide by 80 inches long, so a king-size fitted sheet should wrap around it with enough room to avoid any sagging or bunching. Then, a king-size flat sheet should measure 102 inches wide by 112 inches long, which allows for plenty of overhang and styling options.

Brooklyn Bedding’s bamboo sheet set is made from eco-friendly bamboo viscose and is both soft and breathable. It’s naturally wrinkle-resistant, odor-resistant, and antimicrobial, which can help keep your sleep space smelling fresh and clean. The sateen weave also creates a sheen that our testers found cool and smooth to the touch.

These sheets come in nine color and pattern options, as well as five standard sizes. The sets include one flat and fitted sheet, along with two pillowcases (though twin and twin XL sets have just one pillowcase). They also feature helpful “top” and “bottom” labels on the fitted sheet to simplify the process of making your bed. Plus, Quince offers a generous 365-night sleep trial and free shipping.
