Some attach to the longer top rail—you have to remove them to get them out of the way. Others simply rest on the long rails and are hinged at one shorter side rail so the changing station can be flipped over the rail to hang at the outer side of the play yard. We think it's safer to remove the changing table when not in use so it is out of reach of your baby and any other children. In addition, it is always better to have an active means of attachment to the frame—that is you have to click, snap, button, or strap a changing table or bassinet into place rather than just have it resting on a frame.
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
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.
