We bought two of these beanbags and the price is certainly cheap. The processing of the robust substance is good. However've been to the packing Styrofoam peanuts that were withdrawn from the bags. One must be very careful that zipper and velcro are really as close as possible. The filling is made from crushed Styrofoam and not like other bags of polystyrene balls. Ie the flakes grind and the resulting dust. The filling is also not particularly "plump" and not nearly enough. As an adult, I'm partial to the ground when I lie down on it. Probably we will have to buy more beads. For our children it is enough. Dimensionally stable is not all, however. So no comparison to other quality products.
