We bought this frame for our 2 year old's bed.  She's on the shorter side, so we wanted something low to the ground since decent mattresses are so much bigger now.  I like that this frame keeps her bed within a reasonable height so she can climb in and out on her own.  There isn't much room under the bed, so bed skirts and under bed storage won't work with this.  It can also be a bit of a struggle to retrieve anything that gets lost under there.
