L.,
We bought the Graco Duo Glider when I was pregnant with my second son. My boys are now 5 years old and 21/2 and they both still fit in it( I am hoping it will last through this summer). My older son sits in the back which seems to have more room. Both seats have trays(easy to remove), canopies(the front one comes off), and 5 point harnesses. Some of the things I love about are the large bottom storage space, and the front canopy can be moves forward so if my little one is sleeping or if it is windy, I can block the the wind/light. We only use it now when we are traveling via airports , going downtown for the day, or anywhere where they will need a rest(zoo, amusement parks etc.) My boys are runners and I would not even think about taking them without it. I am not into chasing them all over the place. Even though it is a little bulkier than others, it really is nice because if they both are sleep the seats recline and they are shaded by the canopies. I look at people who have the strollers where the older child can stand but to me I always think, what if they get sleepy. Also, an infant seat that is compatible will fit in the back seat space. Good Luck! We did buy ours online but I do not remember where...wherever it was it was free shipping which was nice.
