I read

Our lecterns harmonize reading, writing and typing and benefit both the user's health and workflow. Desk lecterns allow perfect alignment with the shoulders, avoiding twisting that in the long run causes stiff neck, headaches and other spinal disorders. Wall lecterns can be useful when there is no space on the table, or in production areas, warehouses, laboratories and wherever it is necessary to consult documentation hands-free or where there is no support surface. Healthier and more efficient, try it and believe it.
