  We review the construction of consistent higher-spin theories based on
Chern-Simons actions. To this end we first introduce the required higher-spin
algebras and discuss curvature and torsion tensors in an unconstrained way.
Finally we perform a perturbative analysis of the Chern-Simons theory in D=5
for a non-maximally symmetric AdS(4) background and obtain the required
four-dimensional Fronsdal equations in the compensator formulation.
