For unimodular semidirect products of locally compact amenable groups N and H, we show that one can always construct a Folner net of the form (Aalpha \times Bbeta) for G, where (Aalpha) is a strong form of Folner net for N and (Bbeta) is any Folner net for H. Applications to the Heisenberg and Euclidean motion groups are provided.
