"We purchased this for our son after endless research and much discussion and consideration. We were looking for a stroller that was lightweight, converted between bassinette and seat, and could also take a car seat. We also wanted a stroller that had a suspension as we walk almost everywhere over sometimes poorly maintained sidewalks. In other words, a city stroller, not a mall stroller. We also wanted a stroller that looked good and would stand up to extensive use. The Frog fit the bill well in almost every regard. The engineering is very well thought out. The modular design makes it easy to pack the chassis into the back of our small car (Volvo S40), and then use the car seat adaptor (purchased separately) to function as a travel system. We used the bassinette until he was almost 6 months old. In the bassinette he slept very well on walks, and this was invaluable. The adjustable seat and ability to have him facing us or facing forward is a really great feature. Over the heavy snow this winter we used the big wheels in front, but this isn't as maneuverable. With a flick of the handle you have the small wheels front and just about the most maneuverable stroller imaginable. The individual parts are light and yet strong - an important feature as we live in a city apartment and carry it up three floors. This is very much a stroller designed for European cities where people walk everywhere and elevators are scarce. If you have a big garage, an SUV, shop at malls and live in a suburb/exburb without sidewalks all these features will be lost on you, but even so this is a great-looking and very functional stroller."
