I had been using the colorful 8-panel North States baby gate from the time by babies were 6 months-one year. But once they were learning to climb the gate with their toes in the little holes (and use their baby muscles to pull the entire gate down), I knew it was time for a more sturdy option. This fit the ticket, it's not as large as the North States - but plenty large enough for toddler twins (with more than enough room for mom and/or dad to play in with them as well). It's also a few inches shorter in height to our old play pen, but it's not an issue with our 28 & 29 inch boys because the openings/holes on the play pen are low enough that when they step on them, it's more than tall enough to make them unable to climb over. ... full review
I liked this style of playpen as it gave a lot of room and didnt have thin, easily broken fence pieces. Its thick, has suction cups along the bottom to stay in place on hardwood/tile and had a play wall. While a bit expensive the thickness of the plastic holds up well to abuse, household pets, and teething kiddos. Not having the mesh style panels also made it a bit harder to climb out of. But when my son finally got to the point of not wanting to be trapped in it anymore and able to figure how to pull himself over the top, we took it apart and used it as a baby gate to prevent him from being able to get around the media cabinets/shelves where it keeps him from pulling all our blurays and such off the shelves and from turning off and on the cable box and game consoles.

When your baby is a newborn putting them low to floor can cause major strain on your back so you'll want to shop for a playard that has two levels so you can have them higher when they are younger and then move them lower when they learn to roll over. This model from the popular Graco line does all of this at a reasonable price and has some added features like a mobile and pockets on the side to store, diaper, wipes and such. 
Bassinet: Most playards include a bassinet, which is a convenient option if you’re going to have your baby sleep in it while using it as a travelling nursery. The bassinets in playards differ; some are full-sized and run down the length of the playard, some have options like a canopy which is great if you’re going to be using it outdoors, and some have a rocking motion.
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.
I LOVE THIS!! I have 8 month old twin boys who are getting bigger by the day! They were starting to look a little cramped in their pack and play, so I decided to look for something bigger. I was originally looking at the Joovy Room2, but it is soooooo expensive. This one is awesome for A LOT cheaper. The cheaper price definitely doesn't mean cheaper quality at all. The quality of this exceeded my expectation. My only "complaint," and it isn't really a complaint , is that I wish it had wheels. I was a little worried about the reviews saying how heavy it is, but it actually wasn't as heavy as I thought it would be. I really just drag it around the house. Haven't had to put it in the car and take it anywhere yet. ... full review

This is a great little Baby cage 😉 I mean playpen lol it work perfect to put my almost 2 year old in while I do the things I need so I know she's not getting into crap she knows she shouldn't be touching or climbing on the table and suprisingly she loves it I set it up a bit different to make it bigger but it's like her own little spot with all her toys I am so happy with this purchase the slip on pieces to keep each section straight are great to I wouldn't want one without them it would be a total mess! Excellent quality and affordable price! And much better than those cheap round plastic ones that kids can just push over!
