When I was hired to create a living room for a couple in their early 40's ... Their first words were "We don't want Biege! And we want to be wowed!" So using high contrast colors and designing high backed sofas I was able to create HIGH impact... Just what my clients wanted. Sofas can be a real statement piece in your home.
