As others here have mentioned, it is a bit overwhelming to open three boxes containing about a million pieces. With the instructions in the last box I opened, of course. I have put together quite a few bits of furniture from Wayfair and Ikea, and this was definitely the most complex, and took the longest to put together. However, with a bit of patience and just working carefully through each step, the whole thing came together without any issues. It would have been easier if I had had the space to lay all of the pieces out, and I think that the lack of floor space did make it more time-consuming to put together. 
The quality of the pieces is very good (bearing in mind that this is all veneered MDF, or similar), and the predrilled holes all lined up perfectly. The finally assembled item looks really good- I am very pleased with it.
