The star player is a tufted leather ottoman custom-designed by SoJo Design and manufactured by Amir Khamneipur Design in New York. Ralph Lauren armchairs from Webster & Company in Naples, Florida, mingle with a custom sectional sofa and throw pillows by Christian Liaigre for Holly Hunt, who also created the floor lamp with noir patina over solid bronze.
