I'm designing a bed that is to have drawers under it. It never occurred to

Authoritative answer: "Yes".

depends on the design.

box spring + mattress means drawers end up relatively shallow and low to the
floor.

"Captains bed" type eliminates the box-spring for storage. and a very firm
sleep support.
