I did not end up using two parts yet the piece is still sturdy. The (4) plastic feet did not fit all the way in to each of the metal posts which made the entire shelf wobbly so I just took them out. The behind the toilet piece was awkward to screw in and this was a temporary set-up so I just left it out of the final build as well. I wish the plastic protective mini-feet at all four corners underneath the glass shelving were not as visible but I understand why they are necessary.
