Florence Knoll Table Base Only  

ok.
Without going into detail, you should consider passing on the Knoll table. Essentially, you are going to re-invent an expensive lovely table.. with your new stone top idea.

I can't see the picture, but I can answer your questions anyway.
"Will this base handle the approximately 225lbs of weight?"
Yes.
"And is it worth the $1,700 bucks?"
No.

Wow this forums is great!...
Wow this forums is great! Thanks for the prompt responses.
Essentially I'm looking for a somewhat modern base and I think this one would look nicely.
Any other suggestions with that budget in mind?
I'm about to squeeze the trigger - been sitting table-less for over a year. It will cost me about $750 to edge up the quartzite and another 1,700 to get the base delivered. then would have to buy chairs....
In a perfect world with no budget, I'd buy the Claton table and chairs from minotti 😉

Mark, are you suggesting
that the pairing would be ok if the base were much less expensive? If so, I agree. I've seen complete tables (with wood tops, not marble, but still) for not much more than what Jezebel's seller wants for his base alone; it seems silly to spend Knoll prices for a non-Knoll table.
However, if she's able to find a base for significantly less money, I don't think there would be anything inherently wrong with pairing it with the top of her choice.
I have a Florence Knoll dining table whose large oval top was sized appropriately for my old house... But now I live in a smaller apartment, so here it has a non-Knoll 78" x 42" rectangular top. It's not as dramatic as with the big oval, but I think it looks fine, and I certainly prefer it to all the alternative tables I considered when I moved here.
