The pocketed upholstery springs of the disclosed assembly, made from strips of pocketed springs and intended for use in mattresses or cushions, are connected together in "square" array, i.e., each spring disposed in mutually perpendicular rows, by connecting the pocket sheeting of adjacent strips together between adjacent springs of each strip, the firmness of the assembly being increased by the nature of the interstrip connection, namely, an elongated connection centered at mid-height of the spring coils.
