3 across car seats recs

I have a 2016 Ford Edge and was wondering if anyone had the same car and have been able to fit 3 car seats across. I know it may be do-able but wondering which cAr seats you have. I would have a newborn, 3 year old and 5 year old.

I heard that the Diono was good and slim, but not sure how comfy they are for kiddos to sleep in. We drive a lot and they typically nap in the car.

Thanks for the help.
