Overall for the price, the couch is not bad.
That being said, the way the legs are put in , specifically the ones that require screws does not work very well. The screws cannot go in all the way, causing a wobbly experience. The screws are quite long, and the unit would benefit with pre-drilled holes. 
There is something that looks like someone has manually drawn where feet should go, but is not really correct due to the way the frame is located on the back.
