Very sturdy shelf that I use in my dental practice.  Due to the Covid Pandemic, a lot of the items we used to leave in the patient operatory had to be moved to the outside away from patients.  Fits our needs as far as practicality is concerned, but it arrived in so many pieces that assembly took all of 40 to 45 minutes.  Looking at the photo, it looks like it would take all of 10 minutes to assemble, but be assured this will take some time.
