Most of the fill sold anywhere now is shredded memory foam. I don’t personally find this very satisfying to sit on when I want a beanbag, because I remember beanbag chairs from the 60s and 70s, that were filled with beads made of PVC (and, I think once, one homemade one filled with actual beans).
I had a couple of them in the 80s and early 90s filled with the polystyrene pips, or whatever they were, which flattened over a few years, and had to be refilled.
I am aware that PVC and polystyrene are both terrible for the environment (as is the foam of foam mattresses), albeit, PVC beads will at least last the life of the chair, and can even be used to fill another one.
At any rate, I really, really want a beanbag chair, and a big one.
But what can I fill it with that is safe, or at least relatively so, for the environment, comfortable as a beanbag fill, and affordable (I’m not poor, and I’m willing to invest in something that will last, but I’m not rich, either)?
All suggestions welcome, but ones you have personal experience with are especially so.
