A coil spring supporting grid structure of the type used to reinforce the top surface of a box spring foundation unit is provided with formations on the longitudinal and transverse wires thereof, enabling a snap-in interconnection with a plurality of coil springs to form a spring unit assembly. Each coil spring convolute engaged by the grid structure is supported on a pair of upwardly extending formations from a pair of spaced parallel first wires and is locked in place by means of two downwardly depending formations from a pair of spaced parallel second wires which extend transversely with respect to the first wires to form the grid.
