A Gilded four-poster flatpack can be made at a workbench (Steel framed bench or better) in the workshop of a player-owned house.
Like when making the normal Gilded 4-poster, this requires 60 Construction, uses 5 mahogany planks, 2 gold leaves 2 bolts of cloth, and gives 1330 experience. The flatpack can then be used on a bed hotspot in a Bedroom.
