Corporate mythmaking extols the cheap desks Bezos et al would construct out of sawhorses and reclaimed doors. IIRC -- or at least, as I was told -- they actually tried to mass-produce "door desks" when they first moved into their new offices, but the price was, somewhat ironically, exorbitantly more than buying something from Hermann Miller. (See also the windows that opened to reduce A/C costs, which also increased facilities costs.)

The traditional Amazon desks are typically a piece of wood cheaply fastened to four legs. Think less ornate wood desk and more something a beginner might do as a one day diy project to get into woodworking.
