Well, you know your beardie. But I think it might take quite a balancing act for him/her because of how widely the rungs are spaced (at least as the pic shows). I could just see a leg slipping between the rungs and your beardie scrambling to get back on. But if you do use it, Id secure it to the sides of the tank with something more than those suction cups..like maybe some way you could screw it in or something, so it wont fall with his weight.
