The Suzaku X-ray observatory, launched into orbit in 2005, features a broad X-ray bandpass (0.3 to above 300 keV), CCD energy resolution with an excellent narrow response up to 12 keV, and a low-background Hard X-ray Detector above 12 keV. These attributes are key for helping us to deconvolve the multiple broadband emitting and absorbing components that comprise the complex X-ray spectra of Seyfert 1 AGN. We will present selected recent spectroscopic results from Suzaku observations of Seyfert 1 AGN to summarize Suzaku's capabilities and contributions to Seyfert 1 science. With Suzaku, we can quantify the effects of complex absorption (neutral and ionized absorbers, and partial-covering absorbers) on Seyferts' X-ray continuum. We also deconvolve relativistically-broadened Fe K emission lines, a crucial tracer of the accretion flow in the regime of strong gravity, and narrow Fe K emission lines, indicators of more distant material, thereby accurately assessing the frequency of occurrence of broad Fe lines in Seyferts. We also achieve reasonable constraints on Compton reflection components above 10 keV. Meanwhile, narrow Fe K absorption features detected with Suzaku, XMM-Newton and Chandra indicate highly-ionized and high-velocity absorbing outflows, which can represent a significant fraction of an AGN's energy budget.
