You should use concrete block to build this post. Then build out from the post the back wall of the couch with more concrete blocks. Then build the other post. Then stack the second course onto the first course. Then add the third course to the top of the second course. If you want then you can add a fourth course. Then build the back rest the next course by using adhesive tape. Then you should install the last course of the backrest and adjust the blocks with a dead blow hammer. Add the seat of the couch with more concrete blocks or a piece of wood then add the finishing touches to the couch.
