I'm in the middle of debating whether to get a Jane 360 matrix system and went for demo today. I must say I didn't realise the flat car seat was put in the car like that until I saw it, ie taking up 2 places. I'm sure it's fine for people with just 1 baby, but has anyone used it with their 2nd child and had another car seat alongside the flat matrix? Our car's a Scenic so it's not tiny exactly and dd's car seat is a stage 3, booster with armrests and a back.
Also it does seem a bit of a faff but is it really any more faff than transferring a baby from a carrycot to a carseat when you get in the car?
