Previous work on the coherent states of a cosmological scalar field is extended to illustrate the effect of spacetime curvature on the coherent-state parametrization. Coherent states for the ''flat Kasner'' (''Rindler wedge'') cosmology are constructed as an example. It is shown that the coherent-state representation is invariant under a conformal transformation which does not alter the definition of positive frequency.
