We’ve reviewed organic bedding brands over the past 10 years — these are our top picks for organic flannel sheets, selected for their warmth, durability, and softness.

On the coldest nights of the year, when our fingers and toes feel utterly frozen, there’s nothing quite as comforting as slipping into a warm bed topped with flannel sheets. Within minutes, we’re toasty and cocooned in for the evening. And getting out of bed in the morning? Let’s just say it’s a challenge.

What is organic flannel made from?

Organic flannel is a cozy, sustainable fabric made from natural fibers, most commonly organic cotton, though it can also include other fibers, such as eucalyptus lyocell. Organic flannel is the better choice for our beds because the materials used to make it are grown or sourced without synthetic pesticides, herbicides, or genetically modified organisms (GMOs). Unfortunately, conventional cotton flannel sheets are often treated with pesticides, herbicides, and harmful dyes. (That also means farmers who grow cotton are exposed to these dangerous chemicals, and in some cases, poisoned in the process.) To avoid this, choosing organic flannel sheets is not only better for the environment but also safer for people and farmers, especially those with sensitive skin or allergies.

Organic cotton, the most popular base for organic flannel, is harvested and processed using eco-friendly methods that conserve water and energy. Once the cotton fibers are spun into yarn, they’re woven into a soft, slightly fuzzy texture that gives flannel its signature warmth and comfort. This “fuzziness” results from a specialized brushing process that raises the fibers on one or both sides of the fabric, making it ideal for cold-weather clothing, blankets, and sheets.

Eucalyptus-based flannel, made from eucalyptus lyocell, is a newer and exciting addition to the sustainable textiles market. Eucalyptus lyocell is derived from the wood pulp of eucalyptus trees, which are known for their fast growth and minimal need for water or pesticides. This makes eucalyptus an incredibly renewable resource. The process of making lyocell involves breaking down wood pulp into fibers using a non-toxic solvent in a closed-loop system, so 99% of the chemicals and water used are recycled back into production. This gives eucalyptus-based flannel not only a lower environmental footprint but also a silky, soft texture that feels luxurious against the skin. It’s breathable, moisture-wicking, and naturally resistant to bacteria, which makes it an excellent choice for bed sheets. Plus, it’s biodegradable, just like cotton and bamboo-based flannel!

Organic flannel, regardless of its base material, is often dyed with non-toxic, low-impact dyes, adding to its eco-friendly credentials. Whether you’re wrapping yourself in a flannel blanket on a crisp, cool day or snuggling under eucalyptus flannel sheets that feel like a cloud, you can feel good knowing that organic flannel is a healthier and more sustainable choice for you and the planet. ☁️ 💤
