Pushchair problem

Bought this at the Jericho project for £20 - lightweight and compact and can do for a newborn and older kid as recline separately... Zion enjoyed it. However it doesn't fit through our front door whilst up... So returning it and starting from scratch, guess we'll have to get a tandem though I would have preferred the kids to be able to both look forwards and communicate with each other... And don't want a massively long thing when getting on trains and buses!
