Vintage Womb Chair Fabric Issue: Advice Needed  

I actually did try this once ...
I actually did try this once by working the end of a short piece of drinking straw between the treads of the fabric and spraying glue through it. I masked everything off to avoid the problem of overspray, too. It didn't work; the glue ended up very concentrated in a small area under the fabric and soaked through the fabric enough that you could feel it when it dried.
It looks like the fabric is a bit grubby. And what's the condition of the foam under it? It looks lumpy, possibly dried out?
I'd bite the bullet and have the whole thing redone in a new Knoll fabric.

Sorry for the confusion
This image was pulled of the internet and it demonstrates to a larger degree what is happening to ours. Moreover, our chair has blue Knoll fabric that is quite clean and the foam seems to be in good shape. Literally, the fabric is wrinkled a bit on the curve leading to the top portion of the arm.

I suppose you could take it to a (capable) upholsterer
and have them remove the existing fabric, then put it on again after applying fresh adhesive (my understanding is that the upholstery is affixed to the foam on such chairs).
Maybe you could get a price quote, to decide if worthwhile.

unfortunately that wouldn't work, lifting the fabric any more than two hours after applying it just results in ripped up foam stuck to the fabric or having to apply glue over glue resulting in lumpiness...direct sprayed-on-wrong-side-stuffed-up-fabric-so-emabarased I resigned experience...

Good point-
the upholstery is only partially "un-affixed" so removing it would likely damage the existing foam.
I guess that leaves two options only: reupholstery, or strategically-thrown throw pillow.

Oh, ok, got it.
I get what...
Oh, ok, got it.
I get what y'all are saying about not being able to remove the fabric from the surrounding foam without tearing the foam---but if it were my chair, I'd reason that if the adhesive has failed in one area, it might be about ready to let go on the rest of the chair. I'd probably pluck at it here and there and see how it's holding, just to see what the chances are of being able to undo a section and then do it back up after regluing.
Or I would just scare up the funds somehow to have the whole thing redone. Probably that.

Herein lies the rub, eh?
The underlying issue is that, in order to achieve freedom from the design constraints of traditionally-crafted furnishings, designers turned to new materials and techniques that were not necessarily time-tested. The fact is that much of what me admire was simply not intended to endure the long haul. It was a conscious departure from established and proven technology that allowed new and exciting forms to be economically mass-produced and marketed. Now we rely on similarly talented and inventive restorers to come up with innovative techniques to help preserve examples that we have decided are "valuable" somehow.
Saarinen may well have advised buying a new one.

I would just live with it...
I would just live with it for now if its not that bad. I assume its a vintage example so let it look vintage.

To all
thank you. Based upon your responses we believe that leaving it alone is the best option for us at the moment.
Moreover, we will place it in the nursery and consider reupholstering it in a few years.
It seems appropriate, right, womb chair/nursery?
Blessings

Tktoo makes an excellent point, is buttoning down that unattractive? A lot of what we admire is generally of high quality though, perhaps its just that every object has a weak point and that these pieces were so novel that the weak points...are weaker?
And why is it that the 670 has glued on shockmounts? If it was screwed through it would be more sound, the screw heads wouldn't be seen and they could extend the warranty, is there something I'm missing there? It looks like a case of carrying through a technique for the sake of at best an irrational consistency.

Heath, it's my understanding that
Eames devised the rubber shock mount as a means to allow flexibilty at small-dimensioned critical attachment points. Making them rigid, arguably, would mandate larger or thicker components to compensate for stresses. But you're right in that they present a weak point in the chairs' structural longevity. Again, this has to do with Eames experimentation with unproven technology.
