Up for sale is a very sturdy twin bed of excellent quality.
I painted / distressed the chalky wood frame and made several wax coats about 2 years ago.
The optional "bunky board" depends on the mattress you use.
you use box spring under a mattress then you don't need a bunky board.
I owned only foam mattress and needed a bunky to hold the mattress and lift the mattress to avoid a large headboard gap.
