    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 other brands 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. I’m telling literally everyone to buy it.

Stop early wake ups

If you or your child are waking up too early in the morning, the first thing to check is how dark the room is. Sleepout Portable is made with 100% blackout fabric so you can sleep in wherever and whenever you want.

Sleepout vs. the rest

Most “blackout” curtains are not truly blackout, they are made with woven fabric that only blocks 75-90% of light. We put typical blackout curtain fabric to the test with a 10,000-lux light therapy lamp. The results are en-lightening 🙂.

100% Blackout for any window

The Sleepout Story

We founded originally to help with Mark’s insomnia when we realized a blackout curtain that checked all the boxes didn’t exist. So we left their corporate jobs and invented the Sleepout Portable.

After only one year Sleepout is used in over 25,000 nurseries in America helping children (and their parents) get their best sleep.

How does it work?

Sleepout Portable uses patent-pending suction technology that allows it to stay up on any window as long as you want.

The suction cups attach anywhere along the top of the curtain, allowing you to find the perfect fit, and comes with clever material along the perimeter to lie flush with your window and seal out the light that would usually come in from around the sides.

We use the highest-quality 100% blackout fabric that is lightweight and easy to install and adjust as needed. We know it works because we've tried everything else ourselves! 

Is it machine washable?

You bet! No worries about thrills, spills, or anything else. Life happens! Sleepout is easy to care for. 

Machine wash on delicate cycle with cold water and mild detergent. Machine dry on delicate cycle or hang to dry with the lighter side up on a rounded line.

How do I travel with Sleepout Portable?

That's the fun part! Most sleep products are great for home use - Sleepout is too! - but unfortunately you can't bring your mattress with you to your grandma's. 

Sleepout folds up to be the size of a paperback book. Plus it comes with a handy carrying bag! The kit weighs less than 2 lbs, so it's as easy to pack as your favourite t-shirt.

Can I install them vertically and horizontally?

Yep! There are fastener strips on the long and short ends so you can install the Sleepout Portable both ways.

Does it work with Blinds?

Yes! Simply install the Sleepout Portable behind your blinds, between the blinds and the glass of your window to totally block out any light.

Easy to install!

These work, plain and simple. Pop the suction cups on, Velcro the curtain on, and it’s done. Easy to remove. They don’t look too good if the window is on the front of the house, but oh well. If it lets a sleeping infant sleep, it’s a win.


Easy and use and does the job. We love it for our travels.

Sleep out not only produced a great product to black out our nursery area but their customer support was superb!

Works Great!

Our guest bedroom has blinds that do not block light well. But we love the clean look of the blinds and did not want to hang curtains. These work so well for nights when grandchildren sleepover. First morning light is blocked and they can sleep in a bit. Very easy & durable. Thank you!

Great product!

I ordered the Sleepout Portable Blackout Ccurtains to make the extra room in our house dark so our grandbabies would be able to take good naps and sleep well at our house. They are easy to set up and did the trick; the room is now dark and cozy!
