Product Description
Offer your baby something fun everywhere he looks with the Fisher-Price Jumperoo. It also helps prepare your baby for standing and walking by exercising his leg muscles as he jumps in a safe, stable environment. Promotes Independent, Exploratory Play Featuring a seat that spins 360 degrees so your baby can play and interact from any side, the Jumperoo gives your little one endless opportunities for fun, exploratory play and safe, comfortable movement. Colorful animal friends spin, jump, and pop up while music, lights, and sound delight your baby and stimulate his senses.

A Variety of Features Encourage Developing Motor Skills
As your baby stands upright in the Jumperoo with his weight supported, he prepares his muscles for walking. At the same time, as he moves around to look at or play with the different toys, he enhances his large motor skills. As your baby feels more comfortable, he can start bouncing and jumping--actions that strengthen his legs and build confidence. Additionally, the toys offer a variety of textures to provide tactile stimulation and encourage healthy sensory development. There's also an electronic play area at the front of the Jumperoo that can be activated by your baby--teaching him the relationship between cause and effect.

Designed to Keep Your Baby Active, Engaged, and Comfortable
The Jumperoo encourages long-term, comfortable play. The seat is suspended by three springs that allow children to hop up and down. The springs also provide limited travel from left to right and front to back. The Jumperoo's seat is easily height-adjustable by means of three position straps, so it truly grows with your baby. And to help keep your baby engaged, a motion sensor encourages him to explore and play by rewarding him with an explosion of lights and sounds whenever he jumps.
Safety, Portability, and Compact Size Give Parents Peace of Mind Besides being great fun for your baby, the Jumperoo includes many perks to make parents happy too. First, its safe design keeps your baby secure, even as she moves around, providing a great alternative to walkers. Additionally, the Jumperoo requires no doorway; simply set it up anywhere you choose and take it with you from room to room as you clean, cook, or relax. Finally, the storage tubes simply pop off the base, so you won't have to worry about this toy cluttering up your home.
