This is much too steep of an incline to sleep on, especially if you want to use a pillow. I tried and it gave me a backache. It's very firm you would most likely want to use a pillow with it. It seems to be good quality and perfect for using as a backrest while reading or watching TV, which is what my son uses it for because I just gave it to him after trying it out. I would have returned it but for the fact that it's quite large and heavy once it is opened. Think twice about this one if you're wanting to use it for sleeping on and consider something not quite so steep of an angle.
