Family-owned and operated Kolcraft® was established in 1946; the Chicago-based juvenile products manufacturer began by making playards; over time the company started making plastic products and then expanded into the manufacture and distribution of other baby and child product categories. Today, in addition to being the leading crib mattress manufacturer, the company creates high quality, innovative children's products marketed under the Kolcraft brand along with marketing goods under official licenses. An official fan of America's Favorite Pastime™, the company manufactures Major League Baseball™ juvenile products such as step stools, potty rings and umbrella strollers, giving families something to cheer about as parents share their team allegiance with their little ones. Go team go - make potty training fun with your favorite MLB team. Additional products include Sesame Street® potty chairs.
