What Is a Flannel Sheet Set

When winter’s chill sets in, a flannel sheet set becomes your bedroom’s secret weapon for cozy comfort.
These soft sheets are crafted from brushed cotton with a napped texture that traps insulating air pockets, delivering exceptional warmth.
Unlike traditional cotton sheets, flannel’s quality is measured by GSM (ounces per square yard), with 170–180 GSM providing the perfect balance of softness and durability.
A typical cotton flannel sheet set includes a fitted sheet, flat sheet, and pillowcases—all designed to keep you toasty.
Just follow simple care instructions to maintain their plush feel and you’ll enjoy nights of snug, warm sleeping.
How Flannel Sheets Are Made

Now that you understand what flannel sheets are, let’s explore how these cozy sleep companions come to life.
Cotton flannel starts with carefully selected yarns, either carded or combed, which determine the fabric’s initial quality. Manufacturers then use a specialized brushing technique to create that signature soft, fuzzy surface—a process called “napping.”
Double-napped flannel offers extra plushness, typically weighing around 170-180 GSM. Long-staple cotton ensures a softer, more durable sheet.
After brushing, the fabric undergoes prewashed and finishing treatments to reduce shrinkage and enhance softness, giving you the ultimate comfort for a restful night.
