Carol, if you are into grapevine, here is our dining room table. The glass weighs in at 150 lbs. and the grapevine base weighs in at 225 lbs. The grapevines are over 100 years old and needless to say, the vines are massive.
We saw this table in 'Architectural Digest' magazine back in the 1970's and purchased it at an art studio in the French Quarter of New Orleans. Years later we saw this table again in 'Architectural Digest' but it was only half the size of ours. We visited that same art studio 20 years later, and there was a grapevine table about 1/4 the size of ours. We asked the owner why the table was so small and he said the table bases were so huge and heavy that the artist decided to only produce tables 1/4 to 1/2 that size. He said only six of the size we had were ever produced.
It is a very interesting table and in another decade it will be an "antique".
