Deep Pocket Bed Sheets

Deep pocket bed sheets for pillow-top mattresses, hybrid mattresses, memory-foam beds and any bed with a topper — cut with a 22-inch pocket and full-perimeter elastic that actually holds. Our deep pocket bed sheets are 100% combed long-staple cotton in a 400 thread count percale, cut for mattresses up to 22 in. deep and available in every standard bed size.

Why deep pocket bed sheets became necessary

Measure your mattress before you read any further. From the seam at the top edge to the seam at the bottom edge — not the height off the floor, not the number on the box. That figure is the only one that decides whether a fitted sheet will work, and it is the figure almost nobody has to hand.

The reason deep pocket bed sheets are now a category rather than a detail is that mattresses have grown. A standard mattress was eight or nine inches deep for decades; hybrids, pillow-tops and foam models routinely reach fourteen to eighteen, and a topper adds two to four more on top of that. A sheet cut for a nine-inch mattress on a sixteen-inch one has nothing left to grip with, so the corners ride up the sides and let go — the actual cause of nearly every “my fitted sheet keeps coming off” complaint.

Why full-perimeter elastic matters on deep pocket bed sheets

Full-perimeter elastic is what does the holding on a tall mattress; corner-only elastic simply runs out of leverage. Look at any fitted sheet that has failed on a pillow-top bed and it’s always the elastic that gave up first — usually on one corner, which then compromises the other three overnight. Our full-perimeter construction distributes the tension evenly and keeps the sheet on the mattress the way a fitted sheet is supposed to.

The opposite mistake — too much pocket on a thin mattress

Deeper is not automatically better — matched is better. A very deep pocket on a thin mattress leaves surplus fabric bunched underneath, which is uncomfortable and works loose just as readily. For thin mattresses, the sofa bed and RV cuts are shallow by design and hold better than a deep-pocket sheet ever will.

Deep pocket bed sheets size guide

How to measure your mattress properly

1. Strip the mattress bare
2. Measure vertically from the top piping seam to the bottom piping seam
3. Add the depth of any topper (foam, wool, mattress protector)
4. Match the total to your fitted-sheet pocket — do not over-buy

How to care for your deep pocket bed sheets

• Machine wash warm with like colors
• Tumble low; excessive heat degrades elastic more than fabric
• Skip fabric softener — softener coats the elastic and reduces recovery
• Fold by seating each corner inside the next to avoid setting creases in the elastic

Frequently asked questions

What are deep pocket bed sheets?

Fitted sheets cut with an oversized pocket depth (16–22 in. or more) to fit thick mattresses — including pillow-tops, hybrid mattresses, foam beds, and any mattress with a topper added. Ours has a 22 in. pocket rated for mattresses up to 22 in.

How deep is a deep pocket bed sheet?

Standard “deep” is 15–17 in.; “extra deep” is 18–22 in.; our set is at the deep end at 22 in. Choose based on your measured mattress depth plus any topper.

Will deep pocket bed sheets fit a regular mattress?

They will fit, but the surplus fabric may bunch underneath. For thin mattresses (under 12 in.), a matched pocket depth from our standard cuts is a better choice.

Do deep pocket bed sheets stay on the bed?

Ours do, because of the full-perimeter elastic. Corner-only elastic fails on deep mattresses no matter how deep the pocket — the physics does not work. Always check that a deep pocket sheet has perimeter elastic before buying.
