I ordered 2 bags as a refill for my grand daughters Big Joe bean bag chair....I couldn't tell how big the bags were but I thought 2 bags will be more then enough to fill what has settled....it only took not quite 1/2 a bag! You need 2 people to do this so make sure you have help....we used an empty plastic gallon ice cream bucket as dumping from the bag into the chair is difficult and very messy!! Do a bucket at a time...zip closed and shake the beans toward the top of the chair.....this gets the beans where you want them to go! When finished zip both zippers!! The beans were easy to clean up by hand(not a lot of static) Make sure you get them all...styrofoam beads can be deadly if ingested by children!! Make sure the zippers are closed tight and remove the paper clip!!
