I cannot stress this enough with regards to any type of baby equipment. The number one priority is that it should be safe! Be sure to read reviews from parents and experts and keep an eye on product recalls. I would strongly recommend never buying a used playpen or playard; baby items are recalled all the time, and you’re much better off getting a new model that is proven to be safe.
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.
Even those who embraced the playpen, however, did so somewhat reluctantly (“a necessary evil,” ran one headline), and when I reached for the parenting bookshelf, it seemed the anti-playpen voices began to dominate. In Your Baby and Child by Penelope Leach, I was told that “babies who spend hours confined in cribs or playpens, with few toys and minimal adult attention, are very slow in learning to reach out and get hold of things and that means they are also slow in discovering what can be done with things.” In a book called Smart-Wiring Your Baby’s Brain, we are advised to “minimize the time she is confined to a crib or a playpen during waking hours.” Mavis Klein, in The Psychodynamic Counseling Primer, writes that “it has actually been shown that children of about seven or eight years of age who were, as infants, regularly confined in playpens, are less competent at reading and writing than those who were not so imprisoned”; while John Rosemond’s New Parent Power! warns that “there is evidence suggesting that children who spend lots of time confined in cribs or playpens suffered delayed speed and are less coordinated.”
The play yard clips to the frame at the bottom, which means there is no risk of the fabric moving from its place even if your baby shifts and moves a lot inside it. This is a lightweight play yard thus making it very easy to carry for your next long trip with your little one. The presence of pockets to store your baby’s diapers and wipes helps save space, and makes space for more important items readily available.
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
