Portability: Are you going to be taking your playpen to other houses? Perhaps you might want to spend a day at the park, where a playpen would be a handy way to keep your baby safe and let them play alone while you read a book? If you think you might be taking your playpen outside of the home, be sure to choose one that can fold up for easy transport.
The pieces were super easy to assemble. Just slide the rods on one piece into the holes on the next piece to connect them. I was a little disappointed that the rods/holes were not hexagonal like the instructions state. That would have locked them into position either straight or at an angle. Instead, the rods/holes are round, so the panels move around (accordion style) and won't stay in a straight line. There are suction cups on the bottom of the panels that might help if you're using it on a hard floor or smooth mat, but they're useless on carpet or textured mat.
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.
