We explore the consequences of treating the X(3872) meson as a tetraquark bound state. As dynamical framework we employ a relativistic constituent quark model which includes infrared confinement in an effective way. We calculate the hadronic decay widths of the observed channels. For reasonable values of the size parameter of the X(3872) we find consistency with the available experimental data.
