Traditional Infant Swings Are Large And Clunky. We Believed Swings Would Be Better If They Provided The Back And Forth Gliding Motion That Babies Love In A Compact And Modern Design. That'S Why We Created The 4Moms® Rockaroo® Infant Seat. By Flipping The Swing On Its Head And Moving The Pivot Point Under The Seat, The Rockaroo Provides A Large Range Of Motion In A Beautiful Design That Is Just 1/3 The Size Of Traditional Swings.
