This took me, about 1.5-2 hours to put together alone. I did make a mistake before I learned how the digrams worked, but was able to fix it before moving forward. I will say that the instructions require some logical inference to understand. I don't think everyone would have an easy time with them, but once I got it, it was easy enough to continue. Punching the hole out of the back panel was that absolute worst part. I had to sit there and carve at it with a box cutter then an exo knife. It finally came out, but not very cleanly. I wish they would just pre-cut it.I did require help to flip the entertainment center over at one point, but in a pinch, I'm sure I could have managed on my own. It is *very* hefty. Feels very sturdy, looks beautiful, I'm a happy camper.
