Having just gone through a knee replacement, I have a whole new outlook on things like this that can help make things you formally took for granted (like being able to squat) easier. It was fairly easy to put together, although some of the pins were hard to push in during installation and adjustment. Once together, it is just a matter of putting it in place and adjusting the height and width to your toilet. Other folks had issues with it not fitting a toilet with a tank, but I did not. The one inconvenient thing is that it is in the way of the toilet paper holder. The suction cups on the back legs don't completely stick to the floor, but they do keep it from slipping. This says it's rated for 300 lbs., I'm 135 and it works fine for me, but I can't judge beyond that.
