Double stroller

Julie • Full time mommy to 2 amazing little boys. A 3 year old and a baby born March 16th 2016 🍀
I'm looking for one that can hold a toddler and and infant seat, but also comes with the second toddler seat for when baby is bigger. 
I've looked at the Graco ready2grow and the sitandstand be haven't had a chance to try them out. 
Looking for reviews on those or other suggestions. Must be easy to fold and as compact as possible
