I need a new highchair but don't know whether or not to go for a Tripp Trapp. On the upside it would be good later on for dd2 to always be able to sit at a good height at the table, on the downside I'm concerned that I wont be able to move it easily around the place. When I started to look I was only considering one that folds flat by simply picking up. Now that we're approaching summer I often like to sit outside with the kids to eat meals however given the unpredictability of the weather I need a chair that can be moved in and out of the house with relative ease. The Tripp Trapp looks heavy and cumbersome - is it?
