Abstract: A flexible disposable seat guard is created with an absorbent porous top layer and a watertight bottom layer uniquely designed to conform to the lower back and seat portion of various infant/child seats. The seat guard has flexible sides and corners allowing the stretchable material to conform to the angle of a safety harness and/or safety belt. The seat guard has compressed perforations on the lower back portion to adhere and conform to various infant seats. Compressed perforations are located on the bottom seat portion to allow for complete access to the harness latch.
