I really like the size of this toddler bed and the fact that it is low on the ground.  I think my son, who is currently three will be able to sleep in it for a couple of years. The only thing I would prefer is that the bed had padding or some other type of protective material on the edges to minimize injury in case they bump.  My son got hurt on the first day jumping in.  It was easy to assemble, I liked that.
