One Chair. Three Seats!
The Stack(R) is a multichair with three unique configurations that grow with baby: Highchair, Booster, and Youth Stool.

Multi-Function + Versatility
In its first mode, the Stack(R) offers all the convenience of an everyday highchair with a wipeable seat pad, five-point harness, removable tray, and three recline positions. As baby grows into a toddler, the highchair seat is easy to detach from its frame to create a high-back booster that secures to a dining chair for meals with the tray or at the table. Rubberized, pop-out feet for the booster help protect chairs. For older children, the highchair frame can be used as a stool with a contoured seat and pop-up backrest.

Ultra Convenient
Designed for use in the Highchair and Booster modes, the tray snaps easily onto the armrests for mealtime and slides onto the rear legs for storage. It also includes a removable liner for easy cleaning.
