For an orange chair the F-598 looks kind of tough to me. Hell, the name F-598 even sounds tough, like it's a fighter jet or something. It was made by Pierre Paulin in 1973 and is described as "compact, fluid and works very well in grouped sequences." Um, yeah. Sequences. Okay. Maybe not so tough after all. Each chair in that sequence will cost you $2,295 by the way. Oh, that price is tough! And the fabric selections are "Tonus-3" "Divna 2" "Interglobe" and "Novo". Those sound tough to me.
