If you are looking for a twin, triple, or quad buggy you can do a lot worse than the Adventure Buggy Companies buggy.
We just got a triple for our 15 mo twins and 3 mo son. It replaces our bugaboo donkey which we loved.
The downside is it is not the lightest buggy out there and the lead time is around 35 days.
The positive is it is superbly engineered and made, is so easy to push, and looks fantastic. The positives far outweigh the negatives.
If you have multiples or 3 or more of similar ages this has got to be best out there.
As an aside, I don't work for them - you have to order direct from NZ. I just love it so much I had to tell everyone
