A common mistake made by clients is not understanding scale. Scale is everything. Doing a layout of furniture is very important. It that can and will actually fit. Yes, oversized pieces can be comfortable to lounge in, but will it look to large in the room? More important…will it fit through the door? Furniture is not meant to bend around stairs or a landing. If the room openings are small to a large room, consider using fabrics with a large scaled print. So, measure, measure, measure.
