I have two children now, a four year old and a three month old. I can get the Maxi Cosi baby seat on the back seat and the bigger Recaro one onto the passenger seat leaving me drive in a comfortable position. Much to my frustration I can't get both child seats into the back and have enough room up front to still be able to drive the car. (We have a family car already, but I want to drive my Supra more often). I'm thinking of promoting my four year old to a booster seat in the hope she can sit in the seat behind me.
Was looking for something like this, the BubbleBum! An inflatable travel booster seat that I intend on testing sometime to see if it fits snug and secure into the rear seat. Unless someone has already tried it and would save me a trip to Halfords if it's no good?
