A floor lamp I use along side my bed has had the weight materal (cement?)
in its base break up amd fall out. Now the lamp won't stamd straight
anymore - leans against the wall. Is there anything I can put in the lamp
base so it will stand properly again? Or do I have to buy a new lamp?

Plumbers lead. Fishing weights. et alia.
