About the 3-In-1 Arched Décor Metal Superyard Two-Panel 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 10 square feet to 19 square feet. This baby play yard extension only works with the Superyard 3-in-1 Metal Superyard (ASIN B000U5FOT2), sold separately. Adding the extension is quick and easy. Our baby playpen provides a variety of options for keeping your child safe and secure. The baby gate for doorways can act as a portable play yard, a gate, or a barrier. Our gates and gate extensions are JPMA certified. Easily add this extension to either the Toddleroo 3-in-1 6-Panel or 8-Panel Metal Superyards. Just insert the extension ends into the Superyard as directed. This extension will not work with any other Superyards or play yards. Skid-resistant pads keep the play yard extension securely in place without slipping or scratching your floors, making it safe for carpet, hardwood, tile, and more.
