We love our double stroller!Our 2-1/2 year old loves the "captain's chair" that allows him to stand with a buckle firmly behind him at about waist level. When he's tired of standing or wants to have a snack during our walk, he can sit down and a three-point harness buckles him safely in.While our 9-1/2 month old now enjoys the 5-point harness in the front-facing infant seat at the front, while she was still in her first carseat, it securely snapped in to the front compartment. A buckle ran across around the middle of the carseat securely fastening in the carseat in case the other snap were to fail (which it never did for us).The only problem we had was with the brake units. But when we advised One Step Ahead about our troubles, they FedExed the entire rear wheel/brake assembly and we had it on our doorstep in 2 business days. They took us entirely at our word, and didn't require us to ship anything back.You can see from the product pictures (onestepahead.com) that if both children need to be sitting forward-facing, that this can also be accommodated. We've found it easier to allow our older child to have the option to sit or stand, and this then dictates which direction he faces.A very good product which we would (and have) recommend(ed) to anyone!
