Prima Facie seating

I tend to be very careful about orchestra seating with regard the mezzanine overhang. But the back row of the Golden has the only open seats at the date/time I need if I'm going to see Prima Facie this month.

I looked up images of the set from London, which looks amazing with the floor to ceiling (as it were) library. As far as I could tell, there weren't any catwalks, so I'm assuming all or most of the play takes place on the stage itself. In other words, I'm talking myself into getting one of those back-row tickets, but I wanted to ask the experts first.

Any advice much appreciated.

Good to know! Especially as I bit the bullet and bought the ticket. Thanks!
