You forgot about the Ikea-part, where you have to assemble it yourself, and get more than half-way through the project, before you realize that you're either;
A) missing some important part
B) using an assembly-manual that belongs to an older model and thus doesn't really fit the current type
or
C) realize that the tools provided to you for your do-it-yourself assembly has nothing to do with the thing you are trying to assemble, so you have to try and get them to send you new tools, or improvise with a hammer, duct-tape and instant glue
