Mid-sized strollers provide you with a convenient sized product that will be able to do a little bit of all functions that a stroller can offer. If you were, (for a second) going to compare this purchase to a vehicle, you would consider it a mid-sized 4 door sedan. The Peg Perego Switch would be considered a mid-sized stroller.
When considering these mid-sized strollers, make sure that you are not neglecting any very specific jobs that it may not be able to do, (if you have a dog and you must walk every day, something hardier in the hybrid or all terrain program would be more suited to that job). These strollers usually have smaller or double wheels, so winter or “off-roading” may be out of the question.
