I only have this stroller for a while. Although my Britax stroller I still have at hand is great, the advantage of the Optimo Air is that you can reverse the seat, making the baby face you. This makes me happy because I have a six-months-old little one.
Those new air-filled tires are great. We also went to the mountain resort with this stroller, and it was comfortable; we didn't shake our DS to death 🙂
Another advantage is that it is perfectly alright to attach a universal sibling board to the chassis.
A plus is also the full lay-flat of the seat unit so that even a baby can use it 🙂 The leg rest also adjust, it was three different positions if I remember correctly. The canopy can be extended three times, so even when in the fully reclined position, the baby is adequately protected.
