About the Manufacturer

Moms who know choose Graco. In 1942, Russell Gray and Robert Cone formed Graco Metal Products, in Philadelphia, PA. Through hard work and creative designs they created the world's first wind-up infant swing, the Graco Swyngomatic. They knew they had a hit on their hands but no one predicted that Graco would sell but millions of Swyngomatics in the coming years, becoming one of the world's leading manufacturers of juvenile products in the process.

From then on, whatever category it entered, Graco set the standard: the firm's Pack N' Play Portable Playards, designed by Nate Saint, the son of the Swyngomatic's inventor, was introduced in 1987, and achieved the same kind of success as Graco's wind-up swings. The Pack N' Play is now found in millions of homes across North America. Graco raised the bar further when it introduced the Travel System, the first product that allowed you to quickly click a car seat into and out of a stroller, making life easier for mom and dad by allowing them to move a sleeping infant from house to automobile to stroller without waking the little one up.

Today, Graco continues its tradition of innovation, with products like the aluminum-framed Quattro Tour stroller and the Pack 'n Play SPORT which is the perfect choice for families who enjoy outdoor fun. In 1998, Graco proudly acquired Century Car Seats, combining two of the most respected brand names in baby products, and leading to innovative products like the TurboBooster youth booster car seat.

Today, Graco is a Newell Rubbermaid company, with 1500 associates worldwide. While a half-century has brought many changes to Graco, the dedication and commitment to designing and manufacturing top-quality products that inspire parents and babies alike.

overall great purchase, sturdy and easy to clean

from Long beach, CA – Verified Buyer

This is the third car seat we have bought for grandchildren, but the process to change out the bottom latch for the growth spurt is ridiculously hard. it even gave my My helicopter mechanic husband a headache. if i would have known the latch was so difficult to move i would have bought a different seat. otherwise its a good and sturdy seat.
