Abstract: A dual-seat foldable baby cart adapted for babies to sit in or lie down, basically consists of a commonly known baby cart structure with its two pairs of horizontal frames forward extending longer than a conventional baby cart, whereto a pair of front supporting legs tilting backwardly may be riveted near the front end at a proper position and an extra back frame and an extra foldable awning support assembly may be adequately connected and, thus providing additional room for the baby cart. Meanwhile, an angle adjusting device is installed at the connection where back frames and the lower pair of the horizontal frames of the baby cart are jointed so that the back frames may be adjustably tilted at different angles for babies either to sit in or to lie down. The whole baby cart is constructed in such a foldable form that the whole structure is operated by a pedal lever, easily folded or unfolded by simply stepping down the pedal lever.
