Hi there. I have just purchased a citroen grand Picasso to transport my family including grandparents. Love the car but have been told that it has underfloor storage compartments. Bad news as I have a cybex sirona which won't be safe to use as it has a support leg. I could put it in the middle seat but then it will lose its swivel function as another car seat needs to be pleased next to it and I really don't fancy wrestling my squirming 14 month old into a stationary cybex seat in the middle of the car on a daily basis. Any help on a compact ERF seat without a support leg? Many thanks!
