several things play an important part in this scene. Color, size and placement are all factors. If the room is bigger than 15x18 feet, and the couch is one solid color, then no the lamps are not too much. What other furniture is in the room? Do these two lamps throw enough light to read by? Do they cast shadows in the small room making it look smaller?
The most important thing is - are you happy with them? Do they make the room comfortable for you and yours? you want to be content in your own space. And if the lamps make you so, then even in a small room, they should be there for you. Home is always where you go to feel safe, comfortable and at ease. It may be small, But stained glass is a charming touch.
