You DO NEED A POWER DRIVER to properly mount the stool bars. Without a power tool, I can't get the bars to fit tightly (which is important for it's long term structural stability). For the time being, I did screw it manually, and I can sit on it just fine. It's just that the job won't be complete until I get a power tool...

Other than that, the table is very very easy to assemble. Everything looks great, just like in the picture.
I love this one because it's large enough for me and my dining/kitchen activities, but also compact enough to nicely fit in my small kitchen.
