A baby stroller is a vehicle used to transport one or more children, pushed manually. It's a baby's "transportation tool," requiring assistance to push or pull, and typically consists of a sunshade, seat cushion, bassinet, and dust cover. Baby strollers originated in Europe and have a history of over 300 years. They have only appeared in China for a little over a decade, yet China has now become the world's largest manufacturer of baby strollers. In 2020, the transaction value of baby strollers in China reached 21.359 billion yuan, with 418,700 units sold. Many baby strollers have a minimum backrest angle of 175 degrees because a fully reclined 180-degree position poses a safety hazard.
