Where do you live? We're having ours custom-made, and it's not nearly as expensive as I'd thought it would be.

I would expect that to be a custom item or a salvage find, but I've never actually looked. My table in the middle of the room needs all four legs. :)

Southeast Michigan..the thought crossed my mind but I dismissed it pretty quickly thinking it would be too expensive. Perhaps I should check into it. Thanks for the thought!

There are many companies that sell pedestal table bases. They are not expensive and come in many varieties. You could then make, or have made, a top in a size and material of your choice -- wood, laminate, marble....

I have listed one of many such companies at the link below.

In my last kitchen I had one of those tiger oak round tables. I looked high and low for a booth with a curve (like a c instead of an L) because I wanted to use a round table. I actually had one shipped from an ebay seller in Montana and then reupholstered near my Michigan home because it still cost less than having a custom made one. An L banquette won't really work with around round table. Try to find a rectangular or square one.

Often you see trestle type legs in this kind of arrangement, which is one leg but it goes all down the middle of the table the long way.

Thanks for all the suggestions!

We're in Central Ohio--the guy we're using is about an hour north of us, I think. I'll get the contact info from my husband and find out for sure.
