I recommend my own sleep item, Aracne blackout honeycomb blinds.

Sometimes I dislike the brightness inside the house even during the day. At night, I can't sleep if there's even a little light coming through the window. So, blackout blinds are a must in my room or living room. My previous blind broke, so I ordered an Aracne blackout honeycomb blind, and it's pretty good. It's affordable and blocks light well. I sleep soundly in the morning because no light enters the room. I recommend it.
