We have known the Comfort stroller for 15 years. We started with size [3], [4], and now we use [7]. We really like the swivel wheels; they make the stroller easy to handle. My son and I are very happy to have such a comfortable stroller. Lukasz’s satisfaction and safety are the most important things for me. I recommend the Comfort stroller to everyone. The company is run by dedicated people, and even problems with funding or lack thereof have always found a positive solution.
