Hope somebody can help.
I'm looking for those two metal cushion retainers that prevent the seat cushion on a Rock n Roll bed from sliding forwards. They are made from metal rod, approx 6mm diameter and about 200mm in length.
I don't if there is a particular name for what I'm looking for, or where to find them.
Is this something that is custom made maybe? Or could I actually buy them from somewhere? If so, where???

Any help much appreciated.
Jaymo.
