The formation of wet-pressed tissue webs useful for facial tissue, bath tissue, paper towels or the like is substantially improved by forming the wet tissue web in layers in which the second- formed layer has a consistency which is significantly less than the consistency of the first-formed layer. The fiber support index of the forming fabric is about 170 or greater. The resulting improvement in web formation enables uniform debonding during creping, which in turn provides a significant improvement in softness and a reduction in linting. Wet-pressed tissues made with this process are uniformly internally debonded, as measured by a high Void Volume Index, which is comparable to that of throughdried tissues.
