Five side chairs, one arm chair. Eero Saarinen for Knoll Tulip Chairs with original brown leather seats. Nice patina throughout. Not restored- original dings and dents plus supple worn leather. Very clean but not "new furniture showroom" pristine. If that's what you desire than these authentic early vintage examples can be restored to your liking. If you like the wear then these are amazing
