Our dim view of light
For most of us, regular, restful sleep relies on lower light levels. Our natural instinct is to be awake and doing things when the sun is up. Its rise each morning wakens us intuitively. That's not an issue for people who work 9-5, as for shift workers sleeping during daylight hours can be more difficult. But controlling how much light our bedroom sees is simple. A pull-down blind. A total black out. Controlled by hand, by app or on a timer. We do all of that.
The light blocking siderails and bottom seal make it an ideal sleep aid for young children, light sensitive sleepers, shift workers and daytime nappers. It is perfect for use in nurseries, bedrooms, TV gaming rooms, home cinemas and even photography dark rooms.
