It took a few hours because I did it myself -without a helper. And it is perfect, even though I am not the handiest with tools. The exciting thing is that even with many pages of instructions, it is really due to the "breakdown of each step into the smallest detail" so that it is really hard to make a mistake. Make sure to have a pair of torque pliers to use with the screwdriver so that you can grip the nuts...it will make sure that they are securely tightened and you don't strip the screws! Love that they include a few extra of the screws in case you drop them. It looks great1
