I've used this a few times, but it didn't work out for me, so I put it away. It only includes the main unit, no instructions. I couldn't fold it properly, so I stored it folded up small, and there are creases. Please be aware of this if you are concerned. It will be shipped compactly, so please understand. Due to shipping costs, I am not considering any further price reductions. This is a doctor-supervised dome-shaped sleep aid that blocks out light and supports comfortable sleep. - Model Name: IGLOO Sleep Dome - Features: Doctor-supervised sleep dome - Uses: Perfect for naps and light protection - Color: Blue - Design: Dome-shaped Thank you for looking.
