Sleepout vs. the rest

Most “blackout” curtains are made with woven fabric that only blocks 75-90% of light. On the left is a typical "blackout" fabric available everywhere. We used a 10,000-lux light to compare the fabrics. One is truly blackout, one isn't.

    I was amazed by how dark the curtain made the room even in the middle of the day. It definitely solved the problem of light bleeds better than any alternative I've used.

    I’ve tested two brands from Amazon before and they don’t nearly work as well as these ones. The suction cups and the actual material of Sleepout can’t be beat in my opinion.

    I’ve been looking all for this product since my first was born 4 years ago and I just love that it covers ALL the light. Haha I’m telling literally everyone to buy it.

What makes Sleepout different?

100% Blackout fabric

Sleepout's one-of-a-kind 100% blackout fabric is designed with Thermaguard™ technology to block the outside heat & cold and even street noise. This gorgeous fabric is truly unparalleled and completely stops all light. It is Greenguard® and OEKO-TEX® certified free from any harmful substances.

Thermal insulating

Sleepout's biggest secret? Our blackout fabric pays for itself :). The Thermaguard™ technology in our blackout fabric can save up to 30% of yearly heating and cooling costs. That's up to $510 per year for an average family of four! With energy getting more expensive, now is a great time to invest in thermal insulating curtains!

Locking suction cups

We worked for a full year on Sleepout's patent-pending design to make sure it was the strongest hold possible while only taking seconds to install. These industrial-strength, non-damaging suction cups lock onto any window to stay up night after night.

Better materials

Most blackout fabrics only stop 75-90% of light, and are often treated with toxic chemicals that off-gas into bedrooms when the sun hits them. We make our products to stop 100% of light using the highest quality materials, so your little ones can sleep in darkness — and you can sleep in peace.

Made to last

So many products end up in landfills these days. They are intentionally
designed to be constantly replaced. Every Sleepout product is
specifically designed to last a lifetime of use
. We work with
mechanical engineers and industrial designers to ensure that when you purchase from Sleepout you do not need to buy anything else, ever again.

" This blackout curtain will change the way you sleep."


Sleepout stays up all night — so you don't have to.
