I wish they had come up with all these forever things when my children were younger. There are around 300 hundred dollars. They have a multiple positioning seat and harness system. They seem pretty sturdy to. I got the jogging type of stroller to push my one year old around in. It was a little late to use the younger aspect of the stroller but I can still get a few years of use out of it. Plus if I have another baby then they can use it. Its a bit bulky but jogging strollers usually are. Overall I think its a pretty good stroller better then the cheap 15-20 dollar ones I use to try to use on my oldest that could only be pushed on very smooth flat surfaces.
