Looking for a stroller for two!

So I’m looking for a stroller for a 3.5 year old and a new born. I’m looking for something where my 3.5 year old can stand or sit on a ride along board type thing. I’m looking for something with the board/seat attached to the stroller already. I don’t like the ones you have to attach, reviews say they aren’t sturdy and you have to take them off when you fold the stroller up. Right now I’m looking at the GRECO UNO2duo travel system and the CHICCO bravoFor2 double stroller. Has anyone tried these? Do you have any other reconditions??? Thanks!
