An umbrella stroller is a lightweight, compact and portable baby stroller that has an extendable canopy or sunshade. The name comes from the fact that when the canopy is opened, it resembles an open umbrella. These types of strollers are designed for infants who cannot yet sit up on their own, so they lie flat while being pushed in the stroller. They are often preferred by parents because of their compact size and ease of use, making them perfect for travel or everyday use.
