I'm building a custom outdoor kitchen island at counter height and I need to find some counter-height chairs. The house is mid-century. I found a couple of options at DWR. I like the Bertoia counter stools, but they are too expensive at almost $700 each, and it will probably be tough to find vintage Bertoia counter-height chairs. The Aero counter stool is a good price and looks ok, but it is flimsy. Does anyone have any other recommendations?

not sure where you live, but if you're in the philly area, this place has a large selection. some modern, some not. the site doesnt have product photos - only address etc. They're always friendly there so maybe a phone call and they might be able to help you??
