france and son sofa ... have you seen this model  

Thought I remember seeing a Grete Jalk that looked similar to that, but really I have no idea. Beautiful piece of furniture though.

Weird! Yes that is a France and S

that IS so weird ! this is the second france and son piece found that I cannot seem to find another (previous solid teak table we discussed here) . Leif, do you happen to know the period they used this style exer spring seat? I am surprised it went into the 80's ! thanks for your comments Leif and Zephyr

also, I am without a model to replace the upholstery. Do you think it would have been a one piece long seat and back piece? Would the back cushion piece sit a little above the back bar ?

France and Son used Experspring for seats as early as Spadestolen. The Great Dane line has an eeeeeee spring seat foundation underneath a piece of thin polyurethane and fabric. Your springs seem very far apart. I have a feeling that indicates that the cushions were more solid than most. Perhaps it was a one piece cushion? Maybe it was a sprung cushion with a more rigid structure than most?

And France and S

I see... did Cado not use a cado mark? and no medallion...just the gold brand?

Cadovius purchased the company in late 1966. He also owned Royal System A/S, which made the wall units. In the early 1970s, the company Cado came to exist as the parent company of his two subsidiarys, France and S

A one piece cushion would smoke on that lovely sofa.

I would do a single seat cushion but maybe 2 back cushions. Or one back cushion. Kinda depends on the fabric you choose. Stiffer weaves or those with a very stabilizing backing will look better on full width cushions than softer, looser weaves. The reason is that a softer fabric will tend to creep forward on the cushion and you'll forever have to be smoothing it back in place. Same for the back cushions--the fabric will gradually rotate around the foam. It won't get TOO far because the boxing on the sides keeps it in place, but the top seam will visibly dip in the center. If you do welted seams, this will be more noticeable.

Other than that, go for it! Cushions are not a permanent alteration to the piece. They can always be changed later.

If you do one cushion but with a few tufting button you won't have fabric creep. Incidentally, tufting was invented to keep old school cushioning like horse hair in place, and it keeps the fabric in place too, so it is an appeal to a long standing traditional solution to this problem.

Yeah but then the buttons tend to get loose, even when tied with tufting cord which is pretty stable stuff, and you start pulling them out a bit when you slide past them (she says as she slouches down past button-tufted sofa back, dragging that one button with her on the way). (I have grown to hate that one button) (and yes, I have that tool for tightening and/or replacing buttons without undoing the back of the piece, I just haven't gotten around to doing it because I'm too busy slouching on my sofa!)

Unless they're really deeply tufted, then ok. But that's a whole different look.

Thanks for the insight Leif and Spanky. I appreciate the discussion cause it answers and asks questions i need to think about!

I have some nice maharam divina melange in a lovely felt gray I will use.

Well I checked the frame very carefully and there is nary an unfulfilled 'hollow' for said medallion anywhere.

Your approval is the icing dear Aunt Mark,

with thanks to all

Here it is with one cushion.

And here with three.
