A Bag Chair (aka "Sack Chair") are often confused with bean bag chairs, in that they are huge, comfy, and incredibly soft. While that misconception is perfectly understandable, they are far from the same. Bean bags are fun, and many of us grew up owning one. The problem with bean bags is that often they break, tear, or leak, and end up getting tossed in the trash because the styro-foam bead pellets they are stuffed with get everywhere, and make a big mess. Bag Chairs, however, don't suffer from that same problem, since they are often stuffed with large, soft, urethane foam pieces.
