This is a great pillow when you want to nap during the daylight! The pillow is filled with tiny beads. At first it's weird having it on, but you get used to it quickly. The opening is an oval, so your nose and mouth are not covered at all! It doesn't weigh weigh much, so you don't feel like you're top heavy. We use ours in the bedroom, with a pillow or without. My husband plays in a band and likes to take a nap before he heads out and this makes it easier for those weekend gigs. Now we don't have to put up black out curtains :)
