A dasher board assembly provides enhanced safety, such as for ice hockey rinks. The assembly is constructed so that on low height impacts a dampening material with at least one of a damping coefficient of about 1.7-3.210.sup.4 N-s/m, a spring constant of about 1.5-3.010.sup.6 N/m, and a loss coefficient greater than 0.15, absorbs the impact. On high height impacts both the dampening material and deflection of cantilevered generally vertical polygonal aluminum tubes absorb the impact. The assembly results in a Head Injury Criteria of less than 250 for all realistic scenarios, and a reduction of HIC values of at least 30% compared to an equivalent assembly with a rigid frame.
