I read all of the mixed reviews on how difficult it was to assemble these, but am pretty handy good with wood/tools, and the folks who completed them seemed to like them so I figured I'd give it a shot.  Yes, there are no holes pre-drilled to screw the two steps into but I managed anyway.  Yes, you need to have a very short Phillips screwdriver to fit under the steps to screw them in but I managed.  However, once I got them on and tightened, and then attempted to center the long round pivoting rod through the two guide holes in the step sides, it was slightly warped and didn't fit.  I tried to tap it through with a rubber mallet, and immediately cracked the step side.  So now I've got a rickety, cracked step stool after two hours of pretty hard work and am completely unhappy with this purchase.  Do not buy this.
