Does anyone have one of these? Bought one today for my nearly 4yo, from a local/independent and usually very good baby shop. It's fitted with the isofit fittings, but seems very loose/floppy (for want of a better word!) in the car. It's moving around a lot - I feel it shouldn't be, but can anyone else with one of these seats let me know how theirs is, to compare??
TIA!
