The traditional flat-surfaced desk has been more-or-less unchanged for thousands of years.
People often place a drink on their desk. However, this makes it very easy to accidentally knock the drink over onto (depending on the era) a stack of rolled-up papyrus scrolls, a Gutenberg Bible, or a laptop (Figure 1).
Desks should have a sunken “put your drinks here” area where they can safely spill without ruining your workspace (Figure 2).
This would be a great way for a furniture maker to drum up new business. Throw away your outdated “flat surface” desks and buy a new one!
PROS: Actually practical!
