Eames chairs or a copy?  

@mark84, They appear to me as legit "DSS" variant. Possibly later production (1970s), though seeing the undersides would be needed to confirm. The rubber edge molding shrinks over time so the gaps are normal and in correct location. Curious that nearly ALL of the self-leveling feet components of the white plastic floor glides are missing (except for two on the rear legs of the bottom chair in the middle stack)! Almost as if they'd been broken off intentionally. Additional photos of backs and undersides would go a long way to help determine desirability/value.

It's posts like yours that make me really miss some former DA regulars. Especially @eameshead in this case. He knew this stuff backwards and forwards and was always willing to share.

@mark84,

I happened to notice that you saw my response. Did you see the chairs, too?

...and you're welcome, btw. It was nothing. Don't mention it.

Apologies, I have been trying to get more photos to post a decent reply but I don't think they're coming unfortunately.

Thanks so much for taking the time to reply and the info is very helpful. Hopefully I can get to see the chairs before committing to buying. I'm guessing there would be a DSS stamp underneath them?

Thanks again, much appreciated.

@mark84, "DSS" is the Eames Office model code and won't be marked as such anywhere on the chairs. Lots of variation in construction of these evolved over the years, many having to do with the way the bases are fastened to the fiberglass shells.

Bon chance!

I went to view the chairs and they the real deal! They have the Herman Miller Late Black Strip which puts them around 84-99. I don't suppose you're able to pinpoint a more accurate date from the below photos please @tktoo2?

Many thanks!

@mark84, I don't think I've ever seen an upholstered DSS this late in production! My take is there's sort of a good news/bad news situation involved with the set you've found. I'll start with the bad:

   Upholstered DSS are perhaps the least desirable/collectible model in the fiberglass chair range owing to the near impossibility of restoring or repairing the fabric and/or foam padding and the wider interlocking and stacking bases look a bit too institutional for domestic settings compared with "H", wooden "dowel", or wire "Eiffel" bases.

   The set is missing original floor glides. You're probably looking at close to a C-note for 4 replacements (which may exceed the resale value of one chair depending on your market).

   Instead of to rubber "shock mounts" found on earlier production chairs, these bases are screwed directly to threaded metal inserts in the fiberglass shell isolated by only a thin rubber washer in between. This method was NOT designed nor approved by anybody named "Eames".

The good:

   If photos of the one chair are indicative of the entire set, they are in remarkably good condition despite the missing feet!

   Fiberglass shells are not the dreadful and dreaded "greige"color (too many are).

   The backs and undersides of the shells were not painted at the factory (they sometimes were).

   The stacking bases are of the "narrow mount" configuration which means they're more easily switched out for vintage H, wood, Eiffel, or reproduction bases.

@tktoo2 thanks so much for taking the time to reply with such detailed and useful info. It's very much appreciated!
