A Teak dresser 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 Teak dresser, this requires 46 Construction, uses 2 teak planks, 1 molten glass, and gives 181 experience. The flatpack can then be used on a dresser hotspot in a Bedroom, either in building mode or not. This requires no Construction level and gives no experience.
The cost of making and selling a Teak dresser flatpack from scratch gives a profit of: -1,528
After completing the hard Fremennik Tasks, they can also be traded to Advisor Ghrim in exchange for 113 coins being added to your kingdom's coffers in Miscellania. See Flatpack: Miscellania reselling for details.
