What does Toto mean by "close coupled" ?

[rickst29]

Does this mean that the distance, from a line between the two seat bolt holes and the tank, is shorter than the distance on other models, or something else? Thanks in advance.

Close coupled?

I think that means that the tank is bolted to the bowl.
In the 20's, the tank was mounted on the wall, and connected to the bowl with a pipe.

ALL two piece toilets with the tank attached to the bowl are "close coupled". It has nothing to do with the toilet's measurements.
