Love the second seat!
Haven't had an opportunity to try the second seat out as a seat, but we bought the City Select specifically because of the option to add more seats for future kids. We currently use our second seat for the bassinet attachment. It's such a slick design that you can reuse the parts of the seat for a bassinet. Looking forward to trying out the second seat as a seat soon.
