The Leader In Fabric Safety
Sleepout® Fabric is the only blackout fabric in the world to meet both GREENGUARD® Gold and OEKO-TEX® STANDARD 100.
True 100% Blackout
Unlike woven curtains that claim to be blackout, but don't actually block 100% of light, Sleepout is the only blackout fabric guaranteed to block all light or we replace the curtain for free.

The Only GREENGUARD® Gold Blackout Curtains
Designed originally to protect children in settings like nurseries, the GREENGUARD® Gold certification affirms that our blackout fabric is safe from off-gassing VOCs.
Each curtain produced by Sleepout has passed a multi-day off-gassing test, and our fabric is continuously retested to uphold the certification.
Test results show zero formaldehyde and zero emitting VOCs. To verify our certification and the certification of any other company, please visit the SPOT database.
OEKO-TEX® STANDARD 100
Sleepout® Blackout Curtains hold a product-level certification, ensuring every part of the curtain you receive meets the highest standards. Certified by OEKO-TEX, our fabric is rated safe for direct skin contact. To verify our certification and the certification of any other company, please use the OEKO-TEX® Label Check
