i have found that the marco sky is not quite what other people said, it is umbrella style when folded and looks like a single buggy but it is very dificult to fit in a car boot i have a peugot 206 and the boot is reasonable but the buggy doesn't fit without me putting my back seat down very difficult with a toddler and baby in toe. they say it is suitable from 3 months but i would say more 5 months as the strapes dont support your baby very well. On the plus side i would say if you have a child of six months+ a child from 1 year to 3 years it would be good it is relativly easy to manover around shops and even thogh you have a heavy weight at the front it is not to bad to get up kerbs or onto buses trains etc. it is hard to fio suit your needs especially a double so i hope this helps anyone in that situation. if you have one child i recomend the bebe confort loolas they are absoulty fantastic the Bentlys of buggies.
