For flatpacked version, see Oak armchair (flatpack).

An oak armchair can be built in the chair space hotspot of the Parlour in a player-owned house. It requires level 26 Construction, and 3 oak planks to build. When built, it gives the player 180 experience. Most players create oak armchairs to powerlevel (gain exp. quickly). The Low Alchemy value of the flatpack is 4 coins and the High Alchemy value is 6 coins, the same as an oak chair.

Constructing oak armchairs from 26 to 99 Construction would cost 113,323,511.7.
