Individual chairs can be good sellers depending on the type and condition but there’s a lot of variables in that market. A picture would be handy for a start as said above. Not nearly the same demand for old, large stuff as there once was but leather upholstered swivel desk chairs, windsors, some Scandinavian stuff, all can get good money.
As hot stuff said really, markets pretty down, having grown up with my dad being an antique dealer and earning pocket money loading container of the stuff to go around the world, it’s now pretty sad to see that most stuff has little value due to low demand. If you send me a picture I can ask him for an opinion
