I sat front row center and did not think the deck was high at all - perfect view! Cannot speak to the sides though, and if that cuts off any part of the stage.
I was a few rows back and the view was fine. I will say that on the extreme sides, you will miss some of the action staged slightly upstage. For reference, I was audience right and there was a moment in Act 1, I think it was when Whizzer was wearing the brown leather jacket where I couldn't see him for most of his song until he stepped out further. There was another moment when Whizzer and Marvin are on the bed that was a little obscured. For both parts, I think the first few rows were struggling with the view as everyone was kind of shifting around. I forget if the side seats are sold as partial view but maybe they should be.
