We bought this bed for our 2.5 year old son, as we were transitioning him from his crib and wanted a bed that he would be excited about.  He loves bunk beds, and this is a great compromise, as it's pretty low to the ground for a loft bed.  It's also very solid, and I love the fact that we can lay with him in his bed to read stories without worrying about weight restrictions that are a concern for most loft beds I've seen in this price range.  We used a 6 inch mattress so that it doesn't take up too much room against the rail, and it's perfect.  He's slept in his new bed every night since we got rid of his crib with no issues.
