The analytic predictions from the Self-Consistent Field(SCF) theory for grafted polymer layers are compared in detail with the recent Monte Carlo simulations using the bond-fluctuation model. Quantities describing the equilibrium structure of the brush are derived from the SCF theory and compared with the Monte Carlo data with no free parameter. In most cases the results are in agreement wiht the SCF predictions. Causes for discrepancies are also discussed.
