Tall mattress, short sheets? It's one of the most common bedtime battles out there. You stretch one corner on, and the opposite corner snaps right off. Deep pocket sheets are made to end that fight, and ours are built to stay put once they're on.

What Are Deep Pocket Sheets?

Deep pocket sheets are sheet sets with a taller fitted sheet. The "pocket" is the height of the fitted sheet's sides, the part that wraps down and under your mattress. A deeper pocket gives the fabric enough room to cover thick mattresses, pillow-tops and toppers. That extra room is what lets the corners tuck under instead of clinging to the edge.

Sizing varies by brand, but here's a good rule of thumb. Standard sheets usually fit mattresses up to about 14 inches tall. Deep pocket sheets generally cover roughly 15 to 17 inches, and extra deep pocket sheets are made for 18 inches and up.

How to Measure Your Mattress for Deep Pocket Sheets

A tape measure and two minutes will save you a return. Here's the quick way to do it.

• Measure from the bottom seam of your mattress to the highest point on top, usually near a corner.
• Add the thickness of any topper or mattress protector you keep on the bed.
• Add a couple of inches so the fitted sheet can tuck securely underneath.

That final number is the pocket depth to look for. Then check the size details on the product page before you order.

Deep Pocket vs. Extra Deep Pocket Sheets

If your mattress plus topper lands in the mid-teens, deep pocket sheets are your sweet spot. Push past 18 inches with a plush pillow-top or a thick topper, and it's time for extra deep pocket sheets. Going deeper than you need isn't ideal either. Too much fabric can leave the sides loose and baggy.

That's where fit matters as much as depth. A fitted sheet with a strong elastic grip pulls extra fabric snug, so you get full coverage without the slack.

Why Our Performance® Sheets Make Great Deep Pocket Sheets

Our fitted sheets feature Powerband®, a wide elastic band built in to grip your mattress. It helps keep corners locked down no matter how much you toss and turn. Pair that with breathable performance fabrics, and you've got deep pocket sheets that fit well and sleep cool.

Deep Pocket Sheets for Adjustable and Split Beds

Adjustable bases are tough on sheets. Every time you raise the head or feet, the mattress bends and pulls at the corners. A deep pocket fitted sheet with a firm grip has the extra fabric to move with the bed without popping loose.

Sharing an adjustable bed with separate controls? Split sizes let each side move on its own. Our guide to split king sheets walks through the options, and you can pair them with one of our adjustable bases.
