You could use some old fabric and sew it into a bean bag chair. Maybe even tye die it!!! For the beads get some of that no good useless styrofoam packing which takes like a zillion years to turn back to anything natural. put that stuff in your bean bag chair and jump up and down on it. It might not feel so smooth at first ,but once you use it for a while it will be smooth and comfy. You may also want to sew a zipper in there so that you can add more styrofoam.
