We adore this bed!! Our 20 month old has slept through the night all by herself ever since she started in her big girl bed. It’s very sturdy and can easily hold a child and adult in the bed. It withstands toddler climbinghanging easily. The rails are not super tall, so I recommend getting a thin mattress! We got a 6in mattress and our daughter has never roled or fallen out of the bed. We are SO happy.
