Symbio is 100 procent biodegradable. It has a seat made out of waste pieces from black granite and legs made of oak. The seat is polished. The total weight is about 25 kilos. The legs are placed in drilled holes underneath the stone and if you try to move the furniture the legs will fall out. This means that the furniture will stand in the same spot for a long period of time. One can then watch how nature will slowly eat the legs and all that is left is the stone. With new legs made the seat can be recycle for thousand of year. The one who lives will see!
