Two children can use this frame at the same time, since it splits into a 36.5" high chair and a separate booster or floor chair among its sixteen configurations. The activity center measures 23.5" x 19.5" and carries a 10" seat that rotates a full 360 degrees, with a toy basket below. Three height levels and three tray positions adjust as a child grows. A five-point harness and anti-falling baffle handle safety, and the BPA-free tray is dishwasher safe. Ages 6 months to 3 years, 44 lb capacity, net weight 21 lbs.
