I made a temporary headboard from "floorboard" planks from one of the
sheds and the support (overly constructed for the purpose) that the
boards were fasten to is straining to hold them as they are warped to
buggery so I'd suspect your woods the same?
Almost all shed timber is cheap construction grade spruce, or what a timber
merchant sells as "studding". It should actually be drier and more stable
than joinery quality, having to conform to a BS specification but, as always
with timber, it's the luck of the draw. It's only ever dried to an average
moisture content.
