My son is 1 year and 8 months old.  The bed is ideal if you are just teaching your child to sleep in his bed.  The bed is low.  If a child in a dream decides to get off the bed, he will not fall.  The bed does not have a bottom, you only need to put a mattress.  8 inches tall queen size fits perfectly.  Another adult will also fit with a child.
Good quality bed.  Easy to assemble.
