At the higher end of the price spectrum, you'll see a lot of add-on features. For example, the Graco Silhouette Pack ‘n Play Playard with Bassinet and Changer, about $170, has a removable changing table (with an "organizer" to hold diapers, wipes, etc.) and a bassinet feature. The bassinet has a maximum weight capacity of 15 pounds and the changing table has a weight capacity of 25 pounds. This model also comes with a vibrating mattress, electronic mobile, canopy, console with music, and night light. The manufacturer says you should only use the play yard with children under 35 inches tall.
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.
