Hi all. Hopefully will be buying an mpv soon to transport my 2 lo's (13 months and 3.4 years) and grandparents easily. Now my 13 month old will be going into her big brothers cybex sirona and I will be buying my 3 year old a new forward facing seat. My question is which seat can I buy that will be easily taken off and on as I need to fold the rear seat for passengers to gain access to the 3rd row of seats. My lo's will be sitting in the middle row as this will be the safest for them currently. My research suggests the kiddy guardian pro 2 might be a good option as it is fastened with the seatbelt only and should relatively easy to shift to gain access. Is there any others that are worth considering? Many thanks.
