Jens Lounge Chair trouble locating in calatog

Closest I could find in my Risom catalog was U-320

Sorry one extra response, what year was that catalog mid 50's?

Yes I have seen that same...
Yes I have seen that same style it is quite popular with the exposed wool between the legs but the chair in my photo is quite prevalently lacking that and is all legs, have you seen that before?

It is from the Jens Risom...
It is from the Jens Risom Contemporary Furniture Catalog/Book which, sadly, is undated. If I had to make an educated guess, I'd say its from somewhere around 1955-1958ish. Someone with more expertise on Risom could likely narrow it down further

My catalog is from 1955. I...
My catalog is from 1955. I believe there is a slightly different one from 1957 as well.
I also looked last night, and did not see that specific chair design in the catalog. Even the similar two- and three- seat sofas have the exposed wood rails under the upholstered section.
If I had to hazard a guess, I would say "no" on the Risom attribution, but then again, he has quite a prolific portfolio throughout the years.

Is it possible the chair was...
Is it possible the chair was re-upholstered at some point and the exposed wood base covered by fabric (and the resulting empty space filled with foam)?

By 'prolific' do you mean...
By 'prolific' do you mean there is quite a few designs and variations or what? Are you familiar with labeling? There are no visible marking but I think I will remove the bottom covering and check from there. I think you are on the right track with the 'no' though unfortunately. Still a nice chair though, just would have paid a little less.

By "prolific", I meant he...
By "prolific", I meant he designed and built many pieces (e.g. see 149 listings on furnitureindex.dk, which I don't believe is a complete reference).
And I while I have a decent understanding of his more popular pieces, I always hesitate to make an absolute statement about whether he is the designer of a specific piece, due to his large portfolio.
I have noticed some common traits in hardware and framing detailing that he employed, so please post some photos if you decide to "open her up".

Not to hijack this thread,...
Not to hijack this thread, but I've noticed a lot of furniture that has been attributed and/or marked Risom that appears to be 'corporate'. Is this the primary role that Risom served in the furniture world during the mid-century? It's just interesting to me that he can have designed one chair as elegant to belong in a living room when the next so mundane it looks like it belongs in a waiting room.
Is the more 'corporate' style furniture more of his earlier stuff?

From what I gather
He did both. He designed a lot of furniture for universities, offices, etc., which are more plain than the residential pieces. Still high quality though. Difficult to say which market was larger for Risom... most likely commercial, as is/was the case with Herman Miller and Knoll.

That's true. It just...
That's true. It just strikes me as interesting since the case with (mid-century) Knoll / HM the furniture doesn't change a whole lot no matter the application, whether it's residential or commercial.
