My son bought himself a bean bag chair and of course it was only the cover without the beans, so we got these. 1st, it's on the easier side to fill. It came in a bag with a zipper that was like a funnel, so you can just put that part right into the chair. 2nd, they are comfortable to lay on! 3rd, you're probably going to need at least 2 if not 3 bags to fill most chairs. The one he has is a medium size and this only filled about a third of it.
