I work nights and have been having a hard time sleeping during the day but these curtains have been magical. I am no longer awoken by stray sunlight through my blinds or by the sounds of lawnmowers or traffic. The curtains not only match my room aesthetic but it does a great job decreasing the noise outside. These blackout curtains really black out the room. Not a peep of sun comes through and it transforms my room into "night" and has allowed me to sleep much better. During the warmers days, I have also noticed a slight temperature difference in the room compared to the others since it blocks out the sun and cools the room. Absolutely love these curtains and highly recommend for anyone who just wants a dimmer, quieter, and even cooler room.
