A cushion-mountable electrical outlet system for furniture includes a generally flat body having a lower portion that is positionable beneath a cushion of a furniture article. The flat body has an upper portion configured to be positioned along a side edge of the cushion, and an electrical outlet assembly mounted at the upper portion of the flat body. The electrical outlet assembly is positionable so as to be accessible to a user on the cushion. The flat body is plastically deformable so that the lower portion can be angled obliquely relative to the upper portion.
