Unfortunately the tags are gone from this one. It is about 38" tall, 35" wide, and 35" deep. It is leather and upulostry. It does have a label under the cushion with directions for cleaning and a consumer alert. At the bottom of this label is a S-W which might be a clue to the maker.
TIA, Bryan

really a precious piece!!

I will call it a Boss' chair

Thanks for your photos, but that's different from my chair's mechanism; mine does not have a long shaft and the piece that connects to the seat has more streamlined design.

Does anyone have this flo-tilt mechanism for sale? Perhaps a chair with badly damaged seat but this piece intact?
