Further to A Maritime Bureau?, Additional Examples of Maritime Case Furniture and A Third Sea Voyage, I recently came across this rather shallow, but otherwise full-size mahogany split chest of drawers.

The chest being split, in combination with its shallow depth (fig. 2), would suggest it was made for use on board ship.

Further to the comments and discussion on how furniture (or any item) was restrained aboard ship, An Universal Dictionary of the Marine cites:
CHOCK, a ſort of wedge uſed to confine a caſk or other weighty body, in a certain place, and to prevent it from fetching way when the ſhip is in motion, &c.
LASHING, a piece of rope employed to faſten or ſecure any moveable body in a ſhip, or about her maſts, fails, and rigging: alſo the act of faſtening or ſecuring any thing by means of the rope uſed for this purpoſe. [i]
