I might need to get another one because my teenagers and my pets are all fighting over this foam bag chair. It's big but I think that is what they love about it. It's not at all difficult to set up...you just remove the plastic bag around the foam bag and put that into the cover. Then you move the whole thing around a lot for a few days to get the air into it. It does have a chemical scent that will fade but that is the one and only negative thing I have to say...and it goes away. It's so comfortable and my family loves it.
