Virgin Polystyrene Replacement Filling for any of our furniture pieces. Don't be fooled by fill. It is not all created equal. Most bean bag furniture is filled with recycled polystyrene. This type of polystyrene will feel "clumpy & lumpy" and continue to break down into a powder form resulting in a flat bean bag furniture piece. Kush ease uses only the best quality "A" grade virgin polystyrene. This type of polystyrene is spherical in nature and the cell of the bead has not been compromised. Not only does it not turn into powder, but because the bead is round, it rolls and conforms to your body to create the ultimate in comfort.
