Are you sure the raiser height is appropriate for the back row people to have a clear line to the screen? From the snap doesnt looks like
The back riser is 12" high. That's high enough to see over the front row especially when the front row seats are not tilted. I wanted every seat in the theater to be enjoyable. Sitting in the back row should have an unobstructed view of the screen regardless of how many tall people are sitting in front of you.
Both my rows tilt back I'd love to have gone higher but didn't want to build another step. The rule in my theater is front row people MUST recline! This is not a hard rule to enforce
I didn't want it any higher because I only have 8' ceiling clearance and the projector is mounted above the back row.
