I bought this for my 10 month old son (currently 25 pounds at 12 months) when we went to Washington D.C. and would highly recommend for anyone traveling with a little one. He would get tired of the stroller and would want to be held, there were also times where I wanted him up close with me and not in the stroller. He was very happy and comfortable in this. I have only used the frontal position, facing me so far, I have yet to try any of the other 3 - but its a great product and he loves it. Its also very comfortable with the wide straps and the strap that goes across the lumbar. My husband who is 6'3" 250 pounds and I who am 5'3" 140 pounds, can both wear this - so it also has a wide range as far as who can use.
