This activity center features a three-stage growth design to accommodate developmental milestones. Stage 1 supports sitting, swiveling, bouncing, and play; Stage 2 enables cruising and interaction; Stage 3 converts into a play table. It includes over 25 developmental activities, such as a musical light-up piano with three modes (piano, song, motion sensor), peekaboo clouds with squeaking sounds, a wobble lamb with rattle beads, swaying stars, and a sun bead mover with a spinner. Suitable for ages 4 months and up, it supports up to 25 lbs (11.3 kg). The discovery window lets babies observe their feet and piano while playing, reinforcing cause-and-effect learning and improving sensory development and hand-eye coordination. Clip-on toys can be repositioned to match skill levels, encouraging motor and sensory growth. The seat is made of machine-washable polyester, and the suction bird snack bowl is dishwasher-safe. Assembly requires no tools, and detachable legs simplify storage.
