There are a few key differences between Moon Pods and bean bag chairs. For one, Moon Pods are designed to contour to your body, providing support for your back, neck and head. Bean bag chairs, on the other hand, are more of a general seating option and don't offer the same level of support. Additionally, Moon Pods are filled with a special beads that conform to your body shape, while bean bag chairs are typically filled with styrofoam pellets. Finally, Moon Pods come in a variety of sizes and colors, while bean bags tend to be one-size-fits-all.
