Three legged dining chairs  

If your looking for...
If your looking for something new, I like the looks of Wilkhahn recent edition of Walter Papst's three-legged chair.
Francois Azambourg's 3 legged chair is nice to look at, but I don't know about the comfort of the open back

Hans Olsen ?

Thanks!
jesgord, the Papst chair looks good. Quite a distinctive design, but still purposeful. I like it. Hadn't seen it before. Is it solid oak? I'll have to check it out. The second chair is nice too, but I much prefer the Papst of the two.
robert1960, the Hans Olsen chair is really nice. Well built, unassuming. I had forgotten about it. Isn't there a table designed especially for that chair, with slots where the back of the four chairs slide in to form a circle around the table? It's quite nice on its own, but doesn't go so well with my table I think.
rockland, that is an interesting, arthropodous looking design. Looks to be a bit higher than a normal dining chair? I imagine it might actually be comfortable once you adjust to the seating position. The handle is a great feature. Even so, it's not really my style, but thanks anyway, much appreciated.
I should have mentioned what table I have. Sorry for the omission. It looks like this:

Thanks heaps for the cloe up ...
Thanks heaps for the cloe up of the Prouve table I had alwlays wondered, at home I have a folder on the computer of 3 legged chairs, but most of them have the single leg at the back, though I will look in it for you when I can.
Isn't there a Wegner?
Would you consider having something made in the same material and manner as the table?

A tough assignment!
Seeing the table.
Something simple in the same blonde wood.
Or a lacquered finish, a bold color?
Similar architecture as the base?
Or black powder-coated steel. But comfort may suffer...

Did not know this was first designed in the 50's?
Nice chair.
The Walter Papst that Jesgord posted.

Nice.
I gotta wonder about the structure of that front leg. I'd want a t-shaped steel piece let into a slot in the top of the leg and screwed to the seat. But who knows. It doesn't pierce the seat, does it -- a wedged thru-tenon ? Clearly not. Sure looks neat, anyway.
Who makes the black one you show, jesgord ?
Some other nice examples, Rockland. (The single front leg is infinitely more stable in use than a single rear leg !)

Thanks all!
Heath, there is the Wegner Heart chair (image 1). Is that the one? It is lovely, but maybe not the ideal match. I wanted to see alternatives. Having something custom made in a matching style could be an interesting option, although I would prefer to explore more readily available models first. Vintage if possible, especially as the table is new.
rockland, yes tough indeed. Those are the exact questions I ask myself. But that is a fab chair! I had not heard about Emiliano Godoy before. I like his work. Is the chair ash? In production? Comfortable? I guess the latter could be questioned, at least based on its looks. Going in the other direction, I think black powder coated steel would be a great match. If Prouvé's Standard chair was available with three legs, it might be the perfect choice.
SDR, thanks for the input. Long term stability is indeed key here. But a dining chair also needs to be light. I move mine around frequently.
I read up a bit on the Papst chair in the linked pdf. It was designed to provide various sitting positions, including backwards, where the backrest then provides chest support:
"The curved backrest form, the conical structure of the rear chair legs and the form of the seat platform supported the requirement of a chair that could also be sat upon the other way round in order to promote changes in posture and movement. The backrest then serves as an ergonomic chest support. When the user sits on the chair sideways, the backrest also provides support and functions as a convenient and pleasant armrest. Last but not least, the seat platform, tapered towards the front, facilitates circular grouping of chairs in order to support communication and interaction."
Brilliant, if it works, isn't it? I'd love to try one. I also found a picture of the underside (image 2).
One more thing to consider is that the room is very small, with an oak table on an oak floor. I think the materials need to be balanced with that in mind. Do you all think another light wood, such as ash or beech, would work in this context?

A agree with SDR about a T sh...
A agree with SDR about a T shaped support underneath, I feel a bit unesay looking at the underneath of that! But perhaps its been done some clever way I can't think of.
If you look up the Danish furniture index and search for '3 legged' or some such, quite a few should come from memory, its seemed to be a special challenge for them, if any are in production is another question.

Thanks for the tip Heath
I have the Furnitureindex bookmarked, but wouldn't have thought of searching for "three legged" there. I just tried, but unfortunately it only gave two results: the Ant and a Wegner easy chair. Writing the search term in Danish didn't help. Most three legged chairs are apparently not described as such.

There is
actually a search term for '3 legged' on furnitureindex.
Here it is the search:

Thanks Robert, big help. These are my favourites from that search, a lot of results but unfortunately the single front leg seems to be rare.
It seems The furniture index doesn't like being linked to.

Thanks Robert
A numeral three! Ah...
Even so, it returns mostly easy chairs, stools, and tables. I did find a couple of good looking dining chairs, but I think they would be hard to find.
As Heath notes, this seems to be a rare type.
