I drive an 07 cx-7 and i recently purchased a Diono Radian RXT convertible car seat for my 6 month old son. I tried installing it today (rear facing) and it was a pretty snug fit even in the middle. Has anyone else had this car seat while driving a cx-7? if you have what did you end up doing to make it safer/more comfortable? If not what convertible seat would you recommend (from past experiences) using in a cx-7? thanks!!
