The benefits of a traditional flat sheet
Flat sheets have remained a bedroom staple for good reason. Unlike fitted sheets, a flat sheet lies loosely on the mattress or acts as a top sheet between you and your duvet. They’re easy to iron, space-saving in your linen press, and typically more affordable than fitted options. Many find them more accommodating for deeper or non-standard mattresses, offering a clean, polished look when neatly tucked.
Flat sheets are ideal for layering under duvets, over electric blankets, or even on their own in summer. They’re also an excellent choice for guest rooms and multi-use bedding setups, as they provide a soft top layer without adding bulk.
Flat sheet vs fitted sheet. Which one should you choose?
When choosing between a flat sheet vs fitted sheet, consider how you prefer to make your bed. Fitted sheets have elastic corners and hug the mattress snugly, while flat sheets require tucking for a clean finish—though they allow for more flexibility in size and style. Many people use both: a fitted sheet on the mattress and a flat sheet on top for layering. Explore our fitted sheets for the perfect combination.
How to put a flat sheet on a bed
Placing a flat sheet is simple. Lay it evenly over the mattress with the same amount of overhang on each side. Tuck the sheet under the mattress at the foot of the bed first, then fold and tuck the corners in a hospital corner style for a crisp look. Repeat the process on the sides for a smooth, finished result. This technique helps keep your flat bed sheet in place throughout the night.
