I bought this because I currently sleep in the dining room and have people coming in and out of the area throughout the night. I was just hoping to block out the lights but didnt realize Id be getting the best sleep of my life. Its so cozy and comfortable. There are times when its too hot with all the sides closed up and there are times when its feels just right. If you have a slated platform bed it will be a little difficult keeping it in place but it doesnt change the effectiveness. I love my bed tent!
