  For the nonlinear Klein-Gordon equation in R 1+d , we prove the existence of
multi-solitary waves made of any number N of decoupled bound states. This
extends the work of C{\^o}te and Mu{\~n}oz (Forum Math. Sigma 2 (2014)) which
was restricted to ground states, as were most previous similar results for
other nonlinear dispersive and wave models.
