At first sight, it would appear we are spoiled choice-wise when it comes down to selecting and purchasing a pushchair, push-chair or cart. Public Choice.
You've got to consider weight, width, handle height, shopping basket size. Unquestionably not OK for coarse ground but superb for shops. Dependent on how tall you are some pushchairs can be hard to push because their handle height is high. It perhaps a hard task as the dance industry isn't license-regulated, nor are there instructional wants to teach.
