I would say a single sofa is most comfortable for sitting and It can transform the interior of our home. Recently I had ordered one single sofa from Oriental Creativity at a very good price. You can check this design. I am very satisfied with the purchase.

Chesterfield looks great with exposed brick walls and/or wooden flooring. Of course the classic aged brown leather is popular among mature users but the room has to be big enough so that the sofa becomes the focal point.

Got the real life image of the first sofa, it looks like this.
