Can anyone provide the following dimensions for me?

Height of seated front row viewers top of head (I think might be top of chair if the chair covers an average height person's head)

Height of rear row viewers eyes

I just ordered my 45003's and need to get moving on the riser so it is all done when they get here.

Thanks

Depending on how tall you are in the uprright position in average:

Height of seated front row viewers top of head 42"-43"
Height of rear row viewers eyes 36"-37"

I figured I should have just e-mailed you Roman...Thanks

any time...
