The aim of this paper is to investigate the relations between Seifert manifolds and (1,1)-knots. In particular, we prove that every orientable Seifert manifold belonging to a certain class has a cylically presented fundamental group and it is the n-fold strongly-cyclic covering of a lens space branched over a (1,1)-knot.
