Does anyone have any experience with this 6-panel play yard ? Can it be pushed around by a determined toddler ? How does this compare to Kidco's Playden ?

My baby is 9 months old (22.5 lbs) and I will be starting work soon. He will come to work with me and I hope to put him in something where he can play and sleep. I don't know whether to go with Pack 'n Play's or these paneled play yards. If I go with the paneled play yards, he would have more space but I would have to find some other place to put him to sleep.

Any advice will be appreciated ! Thanks. :)
