The Wayfair Basics® blackout shades really do their job. No sunlight is getting in whichever room you decide to use them in. They are also visually appealing. I have seen many black out curtains that do their job, but they are ugly. I put these up in my bedroom and they really help me sleep past the Crack of dawn. I'm a light sleeper and the sun coming up would always wake me up. They really help me get a little extra sleep.
