Centrers can be difficult to measure, so a trick I learned when working in a machine shop was to measure edge to edge. The distance is a the same (especially when measuring hole centre-to-centre distances drilled in a piece of steel) Say the left edge of seat A to the left edge of seat B.

Takes the guesswork out of exactly where the mid point is and should be easy to get repeatable results from many people measuring.
