Trends circle. What was trendy yesterday isn’t trendy today, but it will probably be trendy again tomorrow. Consider steampunk or “Gothic” fashion. What about furniture?
The Aeron chair from Herman Miller didn’t fit the fashion; it contradicted fashion to be more comfortable. In turn, it set it’s own fashion and many other pieces of furniture, not only chairs, tried to mimic the “un-fashion” of the Aeron.
Is it really fashion that sells well? Or is it function? Gothic and steampunk are very anti-functional. Old school ain’t bad. Perhaps old school fashion sells because some functions never go out of style.
