That is from the early to mid 60´s, after ca 1961 and before 1968.
Never seen a rolling version of this chair before.

Hi Pam.

Its possible it is, but impossible to say from the pics that you posted.
A clear shot from the underside would help.

Hello Again,
Here are a few photos- I also added a pic of the back of the chair- the seams look sort of a rough.
Thanks, Pam

I found this photo on the net -the chair in the middle left side photo looks like the desk chair.

I have never seen one of these chairs with upholstery before, so cant say for sure.
But it looks original to my eyes.
Is it leather or vinyl?

The upholstery material looks like it was hand-stitched but the stitches aren't as even as you'd seen on, say, a Swan chair in leather. The padding also looks a bit lumpy on the perimeter of the seat in the photo that shows the underside. Would it be possible to show a clear, in-focus closeup of the stitching on the back?

What are the indentations in the vinyl or leather from the shock mounts? It looks like the whole base was rotated a couple of inches, except not really because the dents sort of fade off at one end. Weird!

Hello,
I would say vinyl - I never noticed the shock mounts before but it does look odd. Here are some additional photos- hopefully they are a bit clearer.
I did a search and found a few chairs similar on a site Metro Modern- but the shock mounts are different.
I have also enclosed a photo of another chair that I would love to have more info. I was told it was a chair from a library in France. I also saw a pair on 1st dibs but little info. Any ideas?
Thank you for all your help, Pam

I meant more like pics taken from a distance of 8-12" or so, but what you posted is enough to determine that the seams are hand sewn, though I was pretty sure of that before.

It looks more like leather than vinyl to me, only because the pebbling isn't super-uniform like it is on almost all vinyls. You should be able to know for sure if you have a magnifying lens, though. Under magnification you can see pores in leather whereas vinyl is just a solid surface.

Pam – Your second chair reminds me of Mario Botta's Seconda chair. I do not think that attribution is correct, but it might be a good place to start your search.

I could not see small pinholes but honestly it's difficult to see clearly even with a magnifying glass. Thank you for all your help. I appreciate it.
And teakhound- thank you. Hopefully I will be able to post more info. on it in the near future.

I'm a bit of an Arne Jacobsen novice, so could use a little help from the forum.

I recently acquired a Mosquito swivel desk chair (Fritz Hansen model 3115) that was part of a larger swap. The seat/back piece had just been reupholstered in green leather, and not yet re-attached to the base.

The base is the earlier four-leg design. There is a detail that leads me to think that the chair may be part of the very earliest production runs. Most of these Seven series chairs that I have seen online have cross bars under the seat that pass through the circular hub at the top of the central post. However, my chair does not have these bars, nor are there any notches in the hub housing for where missing bars might have been.

My theory is therefore that the original base design only had a circular disk on top of the base to which the seat was screwed. Since this design does not appear to resist moment loads from the edges of the seat very well, perhaps there were more connection failures early on than was acceptable. Arne would've then added the cross bars to better transfer these loads to the base without overstressing the screw connections.

Can anyone shed a little light on my theory (right or wrong) and whether this is documented anywhere? There is nothing that I can find on the Fritz Hansen website. If my efforts turn up nothing, I would then send a note to them to see if they have any archive info.

Thanks.

You are absolutely correct in your speculations Cdsilva.
The earliest desk chairs did not have any added support, only the four screws for the plate in the middle.
And the version with arms had only two arms coming out to the back without any padding.
Later in the 50´s the added small arms that were bent upwards with small rubber pads.
Then they went with the "normal" rubber pads that were used on the 3107 chair.
I guess this happened fairly quickly in the first few years of production.

The problem with the armchairs was that they had to put on the normal rubber pad before the legs/arms were attached to the middle plate which makes it a pain to add new ones when the old pads are dried out.

Thanks for the quick reply, MPH.

So would that then date my chair to between 1955 and a few years afterwards?

Since the seat has been reupholstered and there are no holes yet in the leather, I'm not sure what the condition of the screw holes are. Only one shallow machine screw with washer came with the chair, so I am assuming that there are threaded inserts in the seat material (plywood?). Hopefully those inserts are still solidly embedded in the wood.

On a related note, furniture index lists this chair as model 3113. I've noticed that FH juggled their models numbers around over the years.
