Want guests to feel more at home in your home? Add a big round chair or a circular rug or ottoman.

People react more positively to, and prefer to socialize in, spaces filled with curvy forms and shapes, as opposed to rectangles, according to a new study from Oregon State University.

“Curvilinear forms create warmth,” said Sibel Dazkir, a doctoral student in design and human environment, who conducted the study. “They’re associated with organic forms found in nature.”

The study is believed to be the first to assess the impact of form in interior environments, according to Marilyn Read, associate professor at OSU and chairwoman of Dazkir’s thesis committee.
