Pilot holes: Pre-drill with a bit slightly smaller than your screw. Countersink screws: For a flush finish. Avoid edges (at least 1" from board ends).

Use heavy-duty Velcro strips, wall-mounted brackets, or a freestanding design that slots between the mattress and bed frame.

Only if your sink has pre-drilled holes (or you’re willing to drill new ones). Otherwise, use a deck plate to cover extra holes.
