Can you take the drawing of the model of the chairs that you are using as a guide to determine the radius of the circle that the back of the chairs are? With that info, you should be able to easly determine what wood length and depth is required for the riser.
To figure this out, I'd use the drawing of the chairs from the vendor's website, paste it into Visio, then draw a cirle around the chairs, using the back as a guide for lining up with the drawing. Visio will tell you the radius of the circle, and then you can determine the appropriate length of the chord.
