Designed using motion sensor data collected from hundreds of test subjects, this motorized baby rocker mimics the bouncing and swaying of real parents comforting their infants. Unlike lesser seats that merely swing or vibrate, this rocker employs a patented lift mechanism that gently moves the seat up, down, and side-to-side with a smooth human-like cadence. An LCD control screen lets parents select one of five programs and five speeds to customize the rocker's motion, from a basic side-to-side sway to a sideways figure eight. The rocker will not operate if the adjustable incline seat is unlocked, and it stops immediately when it detects obstacles. The rocker has a built-in speaker that plays five peaceful nature sounds, or your own tracks from a connected MP3 player. The three-point harness keeps infants secure, and a pivoting mobile with plush balls that pop out keeps infants entertained. The black nylon fabric seat unzips easily for machine washing. Plugs into AC. Assembly required. For children up to 25 lbs. that cannot sit up on their own. 24" H x 19" w x 24" L. (17 lbs.)
