GSM (grams per square meter) indicates fabric weight. For flannelette, a higher GSM means more warmth and durability. 170-200 GSM is considered heavy, ideal for cold weather. 120-150 GSM is lighter and more breathable, suitable for mild winters or warmer sleepers.
Yes, but choose 100% cotton options that are OEKO-TEX or organic certified to avoid harsh chemicals. Brushed finishes are gentle, but avoid low-quality polyester blends that may irritate skin.
Wash inside out in cold water on gentle cycle, and tumble dry on low heat. Avoid fabric softeners as they can weaken fibers. Higher GSM sheets generally pill less. Choose 100% cotton over polyester blends for longer life.
It depends on the weight. Lightweight flannel (120-150 GSM) can be used in spring and fall in moderate climates. Heavy flannel (180+ GSM) is best for winter only. Some people use them year-round with the help of breathable cotton fibers.
Check the dimensions: standard single flat sheet is about 66×96 inches. Ensure the sheet has enough length for tucking. Some brands offer deep pocket sizes for mattresses 12+ inches. If in doubt, measure your mattress and add 12-24 inches for proper tucking.
