Loose screws?
When I've taken these chairs apart (and I've taken apart several of them), the screws are usually very difficult to remove. The chance that any of the screws just worked themselves loose is pretty unlikely.
Lusifersum has the disassembly procedure roughly correct, although in most cases, all the screws holding the chair together are Phillips head. Use a large #3 Phillips, or you'll ruin the screw heads. I've seen the Allen screws too, but I think it's only on more recent chairs, and only used on the screws holding the arms to the steel plate. All the internal ones are Phillips.
Once you've removed those screws (2 hiding under each arm on the outside of the chair), you typically need to be "persuasive" with the arm to dislodge it from the plate. A good whack with the heel of my hand usually does the trick. Older chairs will be most difficult. But even newer chairs will often have sticky arms because of excess adhesive used to attach the leather.
Oh.. and for Marko, the factory adhesive is Scotchweld 1838. However many in this forum have recommended something called PC-.
Missing mounts
My inherited chair has had what appeared to be collapsed flex mounts. But dissassembly reveals no mounts whatsoever. So the slack condition must have been some slop of bolts to plywood and couple bolts were missing. And the steel angle armrest connecting back to seat with the 4 holes and 2 holes for mounting leather covered square angle plywood arm base differs from the curved steel as your picture shows. I have not released padded backs and seat from the plywood shells but would like to know how to do that, as reconditioning leather and refinishing plywood shells should be easier and cleaner.
Thanks for any help. Larry
Hmmm-are you sure its a Herman Miller chair??
Your description does not sound like it's a Herman Miller chair.They all had 2 shockmounts per side,and I don't know how one could even stay together without them.Unless somebody cobbled one with bolts here and there.Pictures would certainly be worth 1000 words.
Man, Peter you're a broken re...
Man, Peter you're a broken record. It's bad enough you incessantly tout your services, but when someone disagrees with you you talk to them like they're an ignorant little puppy. Is this the way you want to earn business? No matter how good you are, I have a tendency not to do business with arrogant know-it-alls.

GFYS. I think it would be really annoying to have an appraiser tell me my chair is worth a steaming pile of crap because I put in a frankenstein replacement part. Why not just drill straight through the shells- those bolts wont give out either, right?
And for the record Mr Smarmy, I TRIED having something repaired through you. I sent you an inquiry to price out the cost of regluing shockmounts on an LCW. Your response was "regluing an eames lounge begins at $700". So either you can't tell your ass from an LCW, or you were quoting me for a full 670 lounge. In either case your ineptness cleared up the decision to go with your competitor. Which cost me $50. So at the risk of repeating myself: GFYS.
