Nuna Rava

Al
My 4 month old is 27 inches and starting to outgrow her infant seat, anyone have Nuna Rava? A friend has it for her toddler so we are thinking of purchasing as well... 
Want to know how comfy it is for chunky babies, and also wondering if we have 2 SUVs, should we purchase 2 or is it easily transferable? 
Or if anyone has another recommendation. Thanks!
