Does the Modway Adair need a box spring?

No. It is a platform bed with slats, so a mattress sits directly on the frame.

What mattress size fits this bed?

It is a king-size frame, so it takes a standard king mattress.

Yes. The frame, headboard and footboard are metal with a black finish.

It ships flat and must be assembled, including the headboard, footboard and slats.

Some metal beds develop creaks at the joints over time. Checking and tightening the bolts after assembly helps.

The headboard is part of the frame, so it stands at the head of the bed rather than being optional.
