OMG - I love these chairs!  I'm using two of them in a mid-century modern with a  white Saarinen oval dining table knockoff.   The backs of the chairs are white plastic, which match the table and the orange is a sharp contrast.  The chair is comfortable and surprisingly sturdy - especially given price.  It makes me happy just to look at them :-)

One note on the assembly - the screws go through the little felt pieces on the bottom of the chair.  I made the holes with an xacto knife and a screwdriver.  Why the holes weren't punched at the factory is a mystery to me.
