5lbs Shredded Memory Foam Filling for Bean Bag Chair, Premium Beanbag Stuffing High Density Memory Foam Refill

Would one 5# bag fill a 16 x 16 x 16 inch pouf ottoman?

What does it feel like when lying on it? Do you feel that it's lots of individual bits? Or does it just feel like a memory foam pillow?

Can I use them to fill an outdoor pillow?

Can these be put directly into bean bag or do you advise airing/expanding for 1-3 days?
