I have had a lot of strollers my favorite by far is the Baby Jogger City Series Double. the regular one not the mini..regular seats are taller than the mini. I have had it for 5 years and USE it ALL the time. The in-line is in the garage full of spiders;) This stroller lays (very close to) flat for babies/kids napping, individually as well as the canopies. the seats kinda "sway" when you walk for a wonderful soothing touch for baby. I do know they have a car seat adaptor, I never used one, I just put baby in, and he/she fell right back to sleep because of the sway.So many wonderful features about this stroller. I spent more $ on this stroller the first time, but if you combined all the other ones I have purchased I could have an easy two dozen by now! The handle is adjustable,to fold.. grab the "fold" grips to fold in half one step!, the foot rest are hard plastic which is WONDERFUL for cleaning. My kids all love to push and ride in it. It is 29.5" wide, so it fits into standard doors, goes shopping malls great, amusement parks, mountain trails.Easy to push with one or 4 kids in it(the 5th one made it harder, I think it was the weight issue ;) ) I LOVE THIS STROLLER!! There are a lot of attachments available. I have not used any, the only thing I have a problem with is the handle gripper after the 5 years is torn now, a month ago..but that is IT! Look it up and do your research. My husband who is the "geek" bought this for me. He said it was better than the BOB...seats go back farther, fold system, handle adjusts and a few other things. It turns on a dime, have the option for swivel or straight front wheels. In-lines are hard to turn if the weight is not distributed eaccordingly, both seats don't recline all the way, the leg room runs out sooner than later The list here is endless! But I recommend the Baby Jogger City Series Double..amazon has a few for $499. Mine was over $500 5 years ago. Good luck.
