A safety net system for multi-story building construction includes a plurality of post assemblies spaced around the perimeter of the building, each with a horizontal shaft at its lower end pivoted to a bracket attached to a lower floor of the building, and a safety net suspended between the outer, free ends of the post assemblies end the adjacent upper floor of the building. The horizontal shaft at the inner end of each post assembly is received in annular bearings having inner and outer sleeves and an elastic core therebetween. The bearings are releasably clamped about the horizontal shaft to restrain the post assembly against rotation and lock it in an upright, stowed position or an inclined, deployed position. The resiliency of the elastic core permits limited, upward rotation of the post assembly to absorb shocks from falling debris.
