What length sofa would fit four people comfortably? What kind of cushion/back pillow configuration would work best for four people to sit comfortably in conversation. I see the your way program has a 96 inch option but looks like it would still be just three seat cushions. Would the wider cushions make seating four people more possible or still just a three seater? I am looking for something maybe like the Copley in leather. thank you.
