If you expect to frequently move your play yard from room to room, check its dimensions before you buy. Many interior doorways are only 30 inches wide—no problem for the 28-inch width of most basic models. But many deluxe models are wider—the Graco mentioned above, for example, would be a tight squeeze at 28.8 inches wide. Just be aware that you might find yourself folding a deluxe model to move it around inside the house.
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.
Perfect for a variety of different uses. Having 3 kids under 5, I've used my fair share of baby gates and play yards. The Evenflo play space is very portable, lightweight and easy to fold down and take on the go. You can add and remove sections with a simple push of a button. I'm currently using this gate to block off my fireplace from my one year old who's fascinated with climbing on it. Also, I will be using it during the holidays to wrap around and block my kids from getting into the Christmas tree. I would recommend this gate.
