First of all, keep in mind that a living room is a place to meet people. So it always going to need seats available, so you need to maximize the number of people you want to seat, vs the functionality of the room. 

A couch, or sofa, is a standard focal point for a Living Room. It is used because is the piece of furniture that maximizes seat spaces and beauty in a single design.

Sometimes our spaces are too small to enter a sofa or couch, or the room layout it’s tricky and to place a sofa result in an inconvenience for the rest of the items in the living. For both cases there are alternatives.

The first one is to reduce one seat and go for a loveseat (like the Barcelona loveseat), combined with one or two chairs, depending on the spatial dimensions or the layout conditions. If conditions don’t even allow it, is good to get support with just chairs and a bench, depending on the case. A bench in the style of the Barcelona Bench is a good option to make seats available without overload your room.
