ABSTRACT:
An internal support structure for a mattress which has a plurality of springs oriented in matrix fashion into a plurality of rows and columns, at least one outer border wire extending around the periphery of the matrix and secured to the springs located at the border or terminal rows and columns of the matrix, layers of padding or cushioning material and a fabric cover. The internal support unit comprises an inner border wire structure which is connected to the outer border wire of the mattress and to at least some of said springs. The inner border wire includes four separate wire band sections which overlap one another in a grid pattern and form a closed inner border loop. The ends of each band section are connected to the outer border wire. The inner border wire and outer border wire are concentric and located in the same horizontal plane. The band sections of the inner border wire which are parallel to the longitudinal axis of the mattress are secured at spaced locations to at least some of the springs which the sections overlay. The band sections of the inner border wire which are transverse to the longitudinal axis of the mattress are not attached to the springs which the sections overlay. The overlapping ends of each longitudinal and transverse band section are connected to the outer border wire and form a V-shaped support at each corner of the mattress. The internal support unit also comprises a plurality of spaced apart supplemental bands which join together the two transverse band sections of the inner border wire and form the central portion of the support structure for the mattress.
