I took one star off just because of how narrow the mattress is. I read the reviews that said it was narrow so I wasn't shocked. If you have a camping cot to place it on ot is perfect! I used it on the ground the first night and noticed I kept rolling off. However, once I placed it on my camping cot I slept just fine. I am use to the cot being narrow. I slept very well using the air mattress.
