Described herein are tissue grafts derived from the placenta with improved physical and biological properties. In one aspect, the tissue graft includes a first membrane comprising Wharton's jelly laminated with amnion, chorion, or a combination thereof. The presence of Wharton's jelly in the grafts enhances the performance of allograft amniotic-derived, caderivic allograft, xenograft, or alloplast soft tissue substitutes.
