You can put a sofa without chaise-longue and make it current. The important thing is the sofa design. The upholsteries also help. You can choose a model by modules or put a sofa and place colorful poufs next to it. Do not choose a very long sofa that enhances the rectangular floor of the living room. Play with an intense color on the small wall to visually shorten. Avoid elongated pictures on the walls, it is preferable that you make irregular compositions with square and elongated sheets, placed perpendicular to the floor. Anyway, if the living area is located at one end, with the chaise-longue next to the wall, it will not hinder the passage and you can put it because they are usually 1.85 m long and your living room measures 2.85 m width.
