I was concerned about assemble as my last DYI project (from a box store) was a disaster, so I watched the video 3 or 4 times and once in slow-motion to make sure because this item would be too heavy to return. I am a 68-years old woman who enjoys a DYI project less and less these days (merchandise seems lower quality); however, this was one of the best DYI assemble projects ever. The video is accurate, what you can not see is that the bolts screw into metal washers secured in the holes. That's a huge qualitative difference between this product and others. Those washers grab the bolts so as to ease the placement of the other bolts, then once all bolts are loosely positioned in place, it is easier to tighten them. Excellent engineering idea. It took me about an hour to completely assemble the desk, because my dog kept interrupting and wanting to play. One final mention, I used a silicon kitchen mitt to turn the Allyn wrenches, they are thin and small and the clearance does not permit a 360-degree turn, compromised leverage, at least for me. The silicon mitt provided the grip needed to tighten the screws. As for fit, it perfect in the corner and easy to wipe clean. The bottom shelf in narrow, I wish was it were wider for the printer but all in all this is an excellent product, and highly recommended.
