Excellent for day sleepers

As a day sleeper, this is a total game change I can finally sleep and not be bothered by the light coming through my bedroom window and he keeps my bedroom much cooler. You can definitely feel the difference. Excellent when I have my migraines a nice cool pitch black room.
Definitely worth it !!

Great curtains – easy to set up and finally sleeping past sunrise!

These curtains are fantastic! They were super easy to set up, and they block out the light perfectly. For the first time in ages, I can sleep without waking up at sunrise. Highly recommend!
