No. Baby Bargains talked all about how these were dangerous when your LO gets old enough to escape the crib. It's just gives him an extra evacuation route!
I have one. I am just not a big fan of the changing table I find it really high. I guess it has to be so your LO can't climb it. I change DD on our bed. Its just better that way. Time to time I use the changing table but I'm not a big fan of it. Its a space saver though and when its time to convert its used as an end table. The mattress has levels to go down as the baby gets bigger and able to stand or sit up. I got mine from JC Penney
