Asymmetric spring components for mattress and other flexible support structures, in the form of helical coil springs with turns in the coil body having varying pitch angles and radii, and a single support end for use in a one sided innersprings in one-sided mattresses. The coil springs are asymmetric about an axis of the coil or a horizontal reference plane, or both, and with ends of the coil springs shpaed and sized differently to accommodate different mounting and support arrangements. Asymmetric coil springs can be contained in individual pockets or strings of pockets and arranged together to form an asymmetric pocketed coil innerspring for use in a one-sided mattress.
