About the Superyard Colorplay 2-Panel Door Extension: Our 2 panel play yard extension increases your Superyard (sold separately) from a 6-panel play yard to an 8-panel play yard. It increases the size of the Superyard from 18.5 square feet to 34.4 square feet, that's almost 7 feet across! This baby play yard extension only works with the Superyard Colorplay 6-Panel Play Yard (ASIN B006NTY1HK), sold separately. The plastic play yard extension includes an easy access door with a u-frame panel. This secure door allows adults to easily enter and exit the playpen while keeping children safely inside. The playpen extension is great for indoor or outdoor use. A UV-resistant design keeps colors vibrant and ensures long-lasting durability. The SuperGrip feet and skid-resistant pads prevent movement and protect hardwood floors. Every Toddleroo by North States play yard extension is JPMA and ASTM certified. Proudly made in the USA.
