Pottery Barn’s box spring frame is specifically made to match all headboard-only sets. Its additional headboard adapter kit easily attaches it to the box spring frame.

The Headboard Adapter Kit ensures that Pottery Barn headboards will attach to your bed frame. The kit is not necessary if you have a standard metal bed frame with predrilled holes in the faceplate at 5.5″, 7″ and 9.5″ up from the floor.

Box spring frame comes in four sizes (Twin, Queen, King, California King) and ranges from $60.00-$85.00.

The headboard adapter kit is $12.00
