we have a 2014 cx-5 and looking to fit one forward facing, one rear facing and one infant rear facing. We have a variety of seats currently including- diono 3r, chicco key fit, chicco my fit, graco extend to fit. of course aware we'll need to buy different ones to fit. any suggestions?
I can't say for certain about the CX-5, sorry. I do know that most compact SUVs make it difficult to 3-across with an infant rear-facing only seat. Some are essentially impossible. The width at the handle often makes it impossible, and even if it does fit, the friction from adjacent seats may make it easier to inadvertently prevent the infant carrier from clicking into the base.
The best possibilities are to have two narrow seats for your older kids, one FF and one RF. The Graco SlimFit3 LX and True3Fit are among the nicer ones, but the Diono Radian and others are also similar in width. Then, depending on the vehicle, installing those two side-by-side will sometimes leave just enough room for something like your KeyFit on one side. In many vehicles, you have to try the infant seat on both the driver and passenger side, as the amount of space can vary a bit with a car seat in the middle.
Using a narrow convertible RF for the infant and using a travel vest for the older, forward-facing child are other options in small vehicles.
