Bean Bag chair liner?

Question:I'm trying to buy a bean bag chair online and it's giving me the option of purchasing a "liner" for an extra cost. What is a bean bag chair liner? Do I really need one?

Answers:
you really want one it is a second linner between the "beans" of the bag and the outtter layer in case the bag gets a whole in it all of the beans won't leak out. I know i got one when i ordered my 6 years ago and I got a tear in it and i never lost any beans cause of the liner.

Hope this helps
