We present the results of spectral analysis of the ASCA data for the Narrow-Line Seyfert 1 galaxy (NLS1) Ton S180 and simultaneous ASCA and RXTE data modelling for the NLS1 Ark 564. We model both the primary and reflected continuum as well as the iron K alpha line, the energy of which depends on the ionization state of the reprocessor. We show that the reprocessing matter is mildly ionized, and we find the soft to hard luminosity ratio to be about 2.5. The accretion rate approximately corresponds to the Eddington limit value.
