The base is very heavy and won't tip over if knocked around. The shade is real stained glass and is very solid. Because of the thickness of the glass, the lamp does not put out much upward light. Using two 60 watt bulbs the lamp is great for lighting the desktop on which it sits. The only negative I have for this lamp is that the top screw/knob which holds the lampshade in place does not screw down tightly so the shade spins slightly when touched.
