The outdoor furniture is usually placed just outside the house, on the lawns. The furniture being spoken of here must be such that all the people wanting to be present for the conversation can fit in easily there. After all, the long chats which take place on the lawns usually involve different members of the family or a group of friends.
The three seater sofa is hence a great option for the people, who have a number of people joining in the chats which take place during a particular point of the day or even week. These sofas not only accommodate the people, but do so quite comfortably too.
