Toddler bed acceptable at 15 months?

My daughter is 15 months, she has slept with us since forever. She can get on and off my bed no problems. I mean I watch her closely but she climbs on everything now. The other day I walked into the kitchen to get her cup, came back and my child was in my bathroom sink.. but anyways besides the point. Can she sleep in a toddler bed? With the rails to keep her from rolling off of course.
