Its all-around elastic is intended to hold the sheet in place, and top and bottom tags help identify its orientation when making the bed.

Why it stands out: The combination of long-staple cotton, all-around elastic, and clear orientation tags addresses comfort and everyday bed-making. Limitation: This is one fitted sheet only, not a complete sheet set.

Buying Guide: How To Choose A 400 Thread Count Fitted Sheet
What mattress size and depth should you check?
Match the sheet’s listed dimensions to your mattress size, then measure the mattress depth from the bottom edge to the top surface. Account for any topper you leave on the bed. A pocket depth of up to 16 inches does not necessarily mean every sheet will fit every shallower mattress equally tightly; look for an explicit depth range when available.
What does 400 thread count tell you?
Thread count describes the number of threads in a measured area of fabric, but it does not determine comfort on its own. These options specify cotton and sateen construction. Consider fiber type, weave, pocket fit, and care details alongside the thread count when comparing sheets.
Should you choose sateen or another weave?
The products here use sateen, which the listings describe as smooth or lustrous. If you prefer a particular texture or want a different weave, check the product specifications before buying. Cotton is a natural fiber, while the feel and finish can vary by construction.
Are fitted sheets sold individually?
Yes. Each product in this guide is listed as a fitted sheet only, not a set. If you need a flat sheet or pillowcases, you will need to purchase those separately.
