My 3.5 year old loves this seat and will have plenty of room even with an extra parent tray and extendable handle. This seat was sold to us as a deluxe choice over the previous City Choice model because I feel the seats are smaller which is great for under 3 year olds. I will say that when I first attached it I didn't have the side clips. just in the right spot and my little one leaned back in the basket (we both laughed, neither baby was hurt.) For that reason I tried to attach a picture of exactly where it snaps: There's a circle at the base of The Stroller, which you need to enter the circle, is carved with brackets on the bench (see photo with a red pattern). If installed correctly, the bench will be very durable. Well done.
