Abstract
A reinforcing structure for the corners of innerspring assemblies comprising spaced parallel parts disposed diagonally across the top and bottom sides of the innerspring assembly, spring members at the opposite ends of the spaced parallel parts disposed between the top and bottom sides which yieldably resist displacement of the top and bottom sides relative to each other and clips fixing the structures to the top and bottom sides of the assembly. The spring members are torsion springs comprising a coil and angularly disposed arms and these are disposed with the arms situated in the planes of the sides and ends of the assembly. Optionally, the top and bottom parts are longitudinallly adjusted to vary the distance between the spring members.
