This cool plastic-and-wood hybrid high chair converts from a counter-height high chair (the hi) to a table-height toddler chair (the lo). You just push a button and flip the chair over and lock it into place-- a very slick design. We also like that the HiLo means we won't have to buy a booster seat once Junior starts objecting to the high chair.
