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
This thing is great. I have it set up as a wall spliting my living room in half basically. The panels are sturdy so hold up great when my daughter pulls herself up standing against them. As i have it set up as a wall i did anchor it to the room walls byattaching some Velcro to the room wall with a screw at either end then wrapping the Velcro around a piece of each end section. This has allowed me to create a baby safe area with all her toys and then an adult safe area with no toys to trip over, and itlet meget away with not baby proofing the entertainment center.
