Play-yard frames are typically made of metal tubing. Mesh on three or, better yet, all four sides provides ventilation and allows you to see your baby. Most models have hinges and lock buttons in the center of the top rails. To set up a play yard, you'll need to pull the top rails up so that they're locked, then push the floor down and secure the play yard mattress or pad. To fold this design, you'll need to pull the floor up, and then raise the top rails slightly while pressing the release buttons to unlatch and collapse the top rails. Before assembling or using your play yard, read the owner's manual carefully and keep it handy for future reference.

Nice to keep baby out of trouble at home. Once he became mobile we had to do an "upgrade" as we noticed he was starting to hit his head on the X shaped metal bars. We tried some alternatives but the best so far was wrapping the metal bars with pool noodles (see picture). You'll need 8 pool noodles and some cuts (buy some extra in case you mess up). Use 2/3 of a pool noodle to wrap the internal bars and the remaining 1/3 to wrap half of the external bar. The pieces will also need a longitudinal cut along the length to fit the bar in. You'll also need some small cuts in the middle of the longer piece to fit the center rivet, where the mesh is attached to the bars. We got the pool noodles at the dollar store nearby for less than $10 and since ... full review
