It's easy to find a 21 inch deep pocket sheets, but it's much harder to find one that actually stays in place. When you're shopping for the best fitting sheet that won't come off, look for options that fit the pocket depth of your mattress and have durable elastic stretched along the edges (not just the corners).


If your 21 inch deep pocket sheets are constantly slipping off, it may be because they are too shallow to fit your mattress, especially if you have a high mattress or mattress pad. Deep pocket sheets, which are usually 15 inches or more deep (while standard sheets tend to be between 7 and 14 inches), may be an easy solution to sheet-related problems. Some sheets may fit well at first, but will shrink over time. Fabrics like microfiber are less likely to shrink, but that doesn't preclude more luxurious fabrics like Egyptian cotton, as long as you take proper care of them.

One reviewer wrote, "These sheets are very comfortable and the price is certainly right. Not the most luxurious sheets I've ever slept on, but more than "acceptable. They're not hot, they're not sticky, they don't bunch up under the foot of the bed in the morning, and most importantly, the sofa covers for pets stay in place! I highly recommend these sheets. I bought 1 set and liked them so much I bought 2 more sets."
