convenient system because my baby is 4 months 1/2 in the stroller and his older brother by just 2 1/2 years may travel at the same time. My son gets tired more and it is easier to walk or do quick errands without having to manage or is my son .... The board is valid up to 20kg and my son actually 17 it's perfect !! Only downside, the pose is how dire..difficile. Luckily my husband and his muscles were there to clipper because the system is difficult to implement .. By cons once set, is stable and this is the most important
