7 Nontoxic Blackout Curtains For Better Sleep (2026)

The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.

Our editors are sustainable homeware and decor enthusiasts. These are the best nontoxic blackout curtains made from materials like organic cotton so you can get better sleep.

With all the recent stressors of everyday life, we’re in need of some better sleep; one way to improve rest is with the help of blackout or privacy curtains. Since our bodies are usually regulated by Circadian rhythms and influenced by sunshine (or a lack thereof), curtains that block unwanted light can help get us to sleep sooner.

Whether you’re looking for white blackout curtains or sustainable privacy curtains, we’ve got the goods. These are sustainably sourced with natural materials like linen, organic cotton, and hemp, so you can breathe (and rest) easier.

Why choose nontoxic blackout curtains?

Choosing nontoxic blackout curtains is a simple way to create a healthier home while improving sleep and energy efficiency, but it’s important to understand how blackout fabrics actually work. Many conventional blackout curtains rely on synthetic backings, often made with polyester, acrylic foam, PVC, or chemical coatings, to achieve that total light-blocking effect. While effective, these materials can off-gas VOCs, especially when exposed to heat and sunlight. Polyester itself is petroleum-based, and when layered with chemical treatments to create a “true blackout” barrier, it can contribute to indoor air pollution. If you’re sensitive to smells, have allergies, or are simply trying to reduce your overall toxic load, these details matter.

Nontoxic options typically use natural front-facing fabrics like organic cotton or linen paired with safer blackout linings, or they carry certifications such as OEKO-TEX to ensure harmful substances are limited. While some blackout performance may still require a tightly woven or layered construction, higher-quality brands are more transparent about their materials and avoid PVC and heavy chemical coatings. In addition to blocking light, well-made curtains help insulate your space — keeping rooms cooler in summer and warmer in winter — which can reduce energy use over time.

If you want to darken your room using natural fabrics exclusively, it’s absolutely possible. Start with thick, tightly woven, dark-colored fabrics like heavyweight organic cotton canvas, wool, or dense linen. Darker shades absorb more light, while heavier weaves prevent it from filtering through. Layering is key: Use double curtain rods to combine sheer panels for daytime privacy with thick outer drapes for nighttime darkness. Installing wraparound curtain rods that curve toward the wall helps eliminate light gaps at the sides, and mounting curtains higher and wider than your window frame prevents light from sneaking in around the edges. For maximum darkness, consider layering two dense panels or adding a natural fiber shade (like woven wood) underneath. While you may not achieve 100% pitch-black conditions without synthetics, thoughtful layering with thick, dark, natural textiles can create a beautifully cozy, low-tox sleep sanctuary — no chemical coatings required!

Customer Review | “Before purchasing these curtains from MagicLinen, I have never used blackout curtains before. This was because most of them had plastic or cheap synthetic materials, which I did not like, but not MagicLinen. They use OEKO-TEX certified fabrics for their curtains, which means they are free from harmful chemicals that other companies use. I love this about them and the fact that I am able to have better sleep because of these curtains! Truly the best” – Henry L. (Read all reviews.)

2. Sleepout

Sleepout blackout curtains were created after co-founder Mark Coombs struggled with light sensitivity and insomnia. Frustrated by the lack of high-quality, non-toxic blackout curtains that didn’t require custom orders or a hefty price tag, he set out to create 100% blackout, PFAS-free, GREENGUARD Gold, and OEKO-TEX certified curtains that anyone could use. The result? Sleepout Portable Blackout Curtains, which attach easily to windows in seconds, no drilling or heavy blinds needed. With a white backing that reflects heat, reduces noise, and helps cut energy costs, these curtains are a game-changer for better sleep and come with lifetime support from blackout experts.

Customer Review | “We purchase a travel set for our toddler and loved it so much that we purchased a second set for our guest apartment. We have traditional shades on the windows, but needed something custom to cover full length glass doors that face a bright street light (only at night, so as not to disrupt the openness of the design). Our guests can easily put these shades up with the suction cups if they want. Then they can be quickly tucked away in the closet when not in use. We have both grey and cream colors and they work exactly the same.” – Hillary D. (Read all reviews.)

I feel safe in my home now not having to worry about curtains that are offgassing chemicals into my lungs. I got a blackout curtain rod that curves towards the wall on both ends For use with your curtains and it’s great at blocking out the light that can bleed in from the sides. It’s important to hang the rod higher than normal to block light that can bleed in from the top if you’re serious about a total blackout. Love love love.” – Joe Gordan (Read all reviews.)
