Advice on price Lounge chair Eames  

Hello everyone, I hope you can help me on this one. A couple is selling furniture from their parent's home and they sell a pair of vintage Herman Miller Lounge chairs. Not sure which model it is (EA115/116 ??). It's in leather, without ottoman. They're in great condition. They're asking 800 euros a piece (about 960 dollars). I think it is too much and I'm sure we can discuss the price. But what do you think would be a good price for them? In Belgium prices are higher than in America... Thank you for your advice, Margaux
