On the chairs- Just because you think they are just chairs, doesn't mean that they are. The set designer actually worked for WEEKS with Stro to get those chairs exactly correct for the purposes of the show and the actors using them. They went though a huge trial and error period, and worked meticulously on making the perfect kind- and rightfully so becuase they are the set. The chairs are not bought, they were commisioned by the show and are very specific down to the weight, the individual grooves on the backs where the actors needed to grab them, the height, the distance between the bars on the back, etc. They are not just some IKEA chairs.
Remember - it's the award is for set DESIGN, not set aesthetics. A lot of design went into this set, even if it looks to people like they were mail-ordered from Switzerland.
