Stroller help

I don't have multiples but thought you guys might know a lot about double strollers. (If there is a better spot for this, please let me know) I have a Safety 1st sit & stand right now and the front seat where my younger one sits is pretty small. He won't be able to be in it as long as say a single stroller. Anyways, I want to know if a stroller exists out there that just has 2 spots for sitting/standing like the spot on the back of my stroller. So for 2 older kids to be able to sit on a flat seat, with no back, stand if they want, & be able to get off freely.
