Design is such that it doesn't give comfortable feel. One can't use it for long time seating unless a  cushion is supporting your back. I always use pillows supplied with sofa to support my back. Cushion not cozy and comfortable. Gives a feeling of coir and spring sofa. I purchased only because I wanted to arrange five people seating in my small living room with a low height back, so that I can reach to low sill windows easily. I arranged them at 90 degree . My living room is just 10x12 feet and other sizes were obstructing opening of main entry door. But, will recommend to those who have small living space and don't want to put too much money.
