Parents aren't the only ones concerned with their child's stroller safety. Before the pushchairs ever hit store shelves they are put though rigorous tests. While in Amsterdam, (Bugaboo flew me there to test out the Donkey — review to come!), I learned that the company's strollers undergo more than 200 safety assessments to evaluate a pram's functionality, response to operating forces, and overall stability before the buggy can get its safety certification. From flip-flop tests to treadmills runs, check out the process!
