The Chicco Stack 3-in-1 Multi-Chair offers four configurations in a sleek and simple package that looks great in any kitchen. The Stack transforms from high chair, to full size booster seat, low-back booster, and true youth stool. For infants, the Chicco Stack serves as a comfortable padded highchair, featuring a 3-positions recline, and one-hand removable tray with washable tray liner. It can also transform into a padded booster seat making it easier to transport or freeing the youth stool for use by an older child. For toddlers on the go, the back of the booster seat can be removed to transform Stack into a light weight, easily-transportable low-back booster with 3-point harness. Finally, kids graduate to the youth stool with its clever pop-up backrest. The Stack features a sturdy welded frame and an easy-to clean pad that's both soft and wipeable.
