This was not too difficult to assemble, however, getting it behind the toilet took a little more effort than expected. I had to lift it over part of the toilet to do so. You may need assistance with this part. I also recommend securing as the manufacturer recommended. Put the wall Mount up before placing in front of toilet, it makes it that much easier. Having said that, I’m VERY pleased with my purchase! It is exactly what I wanted and needed. It’s just as advertised. I have a top flushing toilet and it works great with it, plenty of clearance. Very pleased!
