Biedermeier?

[mojocat]

How can I tell if my couch is a true Biedermeier?  Are there any specific markings to look for?
I don't know a lot about antiques.

there are no specific marking's. construction methods will come in to play. you should see mortise & tenon construction dowel's were used in the machine age.

no coil spring use until at least 1828 there after copper coil spring's. there was a revival period of biedermeier in 1860 thru the 1920's. you would expect to find machine construction in the frame work after 1880 or so.

Pictures are needed especially showing the joints.
