What Made Sleepout® Fabric the #1 Recommended?

Sleepout® Blackout Fabric is guaranteed to provide 100% blackout and is certified non-toxic.

For over a century, blackout curtains have often been made with dangerous levels of formaldehyde to cut costs. Sleepout curtains are different. Made with our proprietary blackout fabric, they’re the only ones in the world that meet the highest safety standards—without compromising performance.

How do Your Curtains Control Tempature?

Sleepout® Blackout Fabric has a white backing that is HOA-approved and reflects sunlight back outside to stop bedrooms from overheating. You can save 30% or more on your energy bill by using Sleepout® Fabric on your windows.

Are Your Curtains Easy to Install?

Our Sleepout® Portable installs in less than 30 seconds on any window. Our Other Sleepout® Curtains work with all curtain rods. If you have any questions, please contact us and we will help with installations.

Improved sleep

This curtain is high quality, beautiful and easy to use. Living in place where there’s tons of windows and city lights, this curtain improved the quality of my sleep. Specially my Sunday afternoon naps after a good hike in the morning. . Thank you 😀🙏🏽

Perfectly effective

These not only reduce the brightness but keep my kids’ room in our apartment cooler from the hot setting sun! Bedtime is much smoother with a more comfortable and darker room. Thank you!!!
