Thule Chariot kids trailer with lot's of extra's, like baby sling, adapters for use as standard baby stroller, jogging stroller and bike trailer. We used this trailer for our son for about 2 summers. It is very robust and all is in good shape. This stroller is fantastic and has very good suspension, which is important with small kids. The only downside I noticed is that it a little big for use as a portable city stroller. Would be expensive to ship, but I can deliver it if you are in the Boston area.
