The legs have a little plastic nub on the bottom, I assume to keep from scratching the floor, but it seems to make it a little wobbly. It won't fall over so we are keeping it in place, but flat bottom would be better. Otherwise easy to put together, meaning the holes and screws line up pretty well. Directions are pictures but not hard to figure out. Fits well in the space, easily clears the top of the toilet and the water line at the bottom. Measure your space before you buy.
