How Stable is your furniture? This is special heavy-duty quality material, stronger than an everyday cardboard used for packaging purposes. Our furniture are stable by design. Have you ever tried to crack an egg by stressing it with two fingers at its ends? It's hard, not because of the hardness of the eggshell, but the shape of the egg that takes and shares the pressure. We are following similar principles in design. Elements wearing weight are always supported on multiple points, so a single shelf can even hold for heavy loads.
