Abstract
A spring assembly for an innerspring unit, particularly an innerspring mattress, is provided wherein at least a pair of springs are restricted about their adjacent offset portions of adjacent terminal convolutions in one surface of the assembly so that hinging action between the adjacent offset portions is allowed only to a maximum angle of deflection between the offset portions and thereafter, upon further loading, the pair of springs provide a greater resistance to loading than would be realized without restriction of their adjacent offset portions. Also provided is an improved coil spring for such a spring assembly.
