Metal steps, climbing with bare feet... not a good combination.  I would suggest the manufacture add pads for the steps or change the design to have more of a flat surface on each step.  Also, no gap to climb into the bed, you have to climb all the way over the rail.  

It also is pretty wobbly, but that's kind of expected with this type of setup.  

NOTE - Bunk sits very high off the ground.  Good for head room for futon, but not so good if your child is a little fearful of the heights.
