Most manufacturers make play yards that are designed to move. Many roll on wheels and fold easily and compactly into their own totes, which resemble short golf bags (although less rugged), making them ideal for trips or jaunts to Grandma's. As we've said, basic play yards tend to be smaller (about 28 inches wide) and lighter (about 20 pounds) because they're not loaded with extras. If you can find a model that fits into its travel bag with its wheels exposed, it can make moving through a busy place such as an airport easier. The Chicco Lullaby LX mentioned above does that.
We have a new puppy. We got one of those wire pens for him. Unfortunately, he almost immediately figured out he could climb the cross wires! He was out in a flash. SO we got this pen. It is almost perfect. It will be perfect when we get done. The bars are in general about two inches wide. Those he cannot get through. But the gate is a different matter. The bars around the hinge and latch areas are about a half inch wider--probably to accommodate the mechanics of the gate latch and hinge. But that is just enough wider that our puppy can get his shoulders through. Maybe the rest of his body, but we intervened.
I received all 8 panels as promised in the description from this seller (I noticed some people said they didn't). High quality (he doesn't hurt his mouth of this when he tries to chew on it), it's smooth and easy to assemble. Even if he bangs his head against one of the gates, he isn't screaming as if it was wood - we still watch him in this because he's not old enough to not watch him but he easily moves around without problems. Colors are great, gate works really well, and its a perfect size for us - gives our 9 month old Baby enough room to play with different items but is not so huge its cumbersome in our place. Suction cups work well too (we have wood floors) and even with the ABC mat underneath, there are points where we can still suction it to the floor so it continues to not move. Overall, its awesome.
The Graco Pack N’ Play Playard Totbloc with Carry Bag is another large-size playpen that provides ample room for baby to roam around and explore her world. It has a clean, modern design with neutral colors to match just about any decor. This playpen is certified frustration-free and sets up in under a minute. It weighs in at around 25 pounds and comes with an easy-to-use carrying bag for travel and storage convenience. At $80, this playpen is right smack in the middle of the cost spectrum, and it comes with no extras such as a bassinet or changing station. Consumers report that the bottom of the playpen tends to slope inward, which can cause toys to pool in the middle; because of this, it is not ideal for baby napping. This product is not free of PVC and phthalates.
