The seat is easy to assemble. With my father I had to remove it from the standard toilet and the increase in the existing screw mounting holes only the ancient seat. Budge and the armrests are installed in 30 seconds without much geschraube or wrangling, not even tool was needed. One can the armrest, at least with my father, completely folded away to the back, they are very easy to move. To change the seat height is not an issue, choose the new height just tighten - all good. Great product. Can only be recommended.
