I think it depends on weight. We used a double stroller at DW with our sons at 5 and 2 very easily. However, it was a side-by-side. Front to back seem to be next to impossible to push even with young toddlers, IMO. We used to take our Graco side by side umbrella stroller all the time and it was sooo easy to fold quickly to get on and off of the buses, through the park, etc. LOVED it!
