For sale, we have this elegant Mid-Century Modern teak headboard for the king-size bed and two nightstands. The metal bed frame is optional (photos show the metal frame set up for a queen-size bed).
We stripped, sanded, and refinished the headboard and nightstands, and they are in good structural condition with some small blemishes that could be seen on close inspection (check photos).
The headboard is W 83 " and stands at H 35" (just the headboard H 18.25"); the nightstands are each: W 18" x D 16" x H 20".
The headboard could be used with the metal frame as shown in photos and the mattress box or you could put a plywood board and put the mattress on top (especially great if the mattress is thick). The third option would be to use it with any platform bed that you might have.
The metal frame is 7.25" high at the spot where the plywood or mattress box would go.
