If your play yard is going to function mostly as a play space for your baby, or you're on a tight budget, you can probably go with a basic model and skip the accessories such as mobiles and bassinet insert. A pair of lockable wheels or swivel casters on one end of the yard will make it easier to move from room to room. If you'll use it for travel, you'll want a play yard that's lightweight, folds quickly and compactly, and has a carrying case. You may even want to be able to roll the packed unit. A carrying bag that allows the play yard's wheels to roll when it's packed is ideal.
Portability: Are you going to be taking your playpen to other houses? Perhaps you might want to spend a day at the park, where a playpen would be a handy way to keep your baby safe and let them play alone while you read a book? If you think you might be taking your playpen outside of the home, be sure to choose one that can fold up for easy transport.
Bassinet inserts can provide a nice place for newborns to nap. Look for a bassinet that securely fastens to the play yard in a way that prevents older children from dislodging or tamper with it, especially if you have other kids in the home or plan to use the bassinet for your next baby. Some of the models we tested in the past had bassinets that attached to the play yard with easily disengaged bars or exposed plastic clips. Older children could easily undo those fasteners, and that could cause the bassinet to fall to the play-yard floor. But one play yard we tested had bassinet clips that are covered by fabric flaps that are locked into place with a button, hiding the clips from view and protecting them from curious fingers. That's a safety plus.
It's helped us out tremendously. It provides a way for us to cordon off a safe space for our son while allowing him an area to freely move. The fact that it breaks apart and can be arranged in various patterns allowed us to expand that space with some creative use of furniture. Sadly though like all young raptors, he's testing the gates, looking for weaknesses that he'll eventually use to escape and terrorize the local populace of cats.
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
