In this paper, we have constructed a sequence of soft points in one soft set with respect to a fixed soft point of another soft set.The convergence and boundedness of these sequences in soft ∆-metric spaces are defined and their properties are established.Further, the complete soft ∆-metric spaces are introduced by defining soft ∆-Cauchy sequences.
