It's easy to put together and take a part. The stickers were hard to place but that's not a big deal to me. My son, now almost 10 months, hates being confined. The play pen was very sturdy but he wouldn't stay in there without crying. I ended up buying another one and using sections of the pen to block off areas of the house. It's not as sturdy when not put together in a closed shape, but it works for us.
I love this pen. It's bright, bulky enough so it's sturdy, but not extremely heavy so it's not hard to handle. Easy to put together and take apart. I bought 2 sets to make this pen twice as large. There is so much space to play and I still have so much room for more toys. I actually need more toys for it! I also love the handle on each gate. It allows me to hang crib toys and dangly toys from it. No toxic odors. Only thing I wasn't happy about was that 2 of the plastic feet to hold up the gate, came damaged. It wasn't packaged right, these 2 feet were cracked right down the middle so I took off a star. Also, the activity panel is pretty boring for my 1 and 2 year old. They found it interesting the first couple if days But it doesn't do much and they quickly lost interest. But my babies do love their baby jail.
Roll with it. Some manufacturers claim that their play yards fold compactly and easily, which is especially important if you'll be traveling with it or assembling and disassembling it often. See for yourself how easy it is by practicing on floor models in the store before you buy. Some parents find that while they can collapse their play yard in a jiffy, fitting the whole thing into its travel bag is almost impossible. If traveling with the play yard is important to you, look at the travel bags when you are shopping.
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
