Toddler beds with "built in" rails - Are they safe?

[smiley76]

I've seen many toddler beds with wooden or plastic "walls" are they safer than the notorious rails?

I have the exact same question! Are beds with rails that are attached to the bed already safe? I have seen various wooden beds with rails at the top of the bed. I assume you would loosen the screw and remove them when the child no longer needed them, or graduate to a twin. I would think as long as the mattress fits properly, it would be fine, as these rails can´t be pushed out to create a gap where the child could get stuck. However, I am not sure and would love the authors´opinion on this matter.
