How wide of a bench and food board are these designed for? Also will they work with wood bench seats?

This page says “Signature Series 3 Row Bleacher ” but the photo has what looks like a picture of a 5 row frame. Is this the 5 row or 3 row series in the photo?

Hi Matt, good question. The photo shown is just a stock photo of our under structure. You correct that a five row is shown. A three row is very similar just three rows instead of five.

Do you have the dimensions and schematic for the 3 row version? I see it for the 4, but not the three.
