I am shopping for a high chair for my 4 month old. I like the durability of the Evenflo and the length of use as it converts to a table and chair. But I like the features of the Chicco Mamma (wheel casters, etc.) Some help and opinions out there? Does the Chicco have a smaller tray as one of the problems with the Prima Pappa I've read is that the tray is too high for smaller infants, etc.
