Bed slat replacement, use on platform beds, bunk beds, or daybeds. Brand new, we assembled then disassembled them. They did not fit on our odd sized bunk beds, but it was the bed that was off, not the bunkie boards. They are a standard size.
Bought new for $100. We have 4 twin size and 2 full size.
