Tatum, a modular seating collection with a distinctly contemporary attitude, features bold track arms and deep seating comfort, enhanced by big toss pillows. Generously cushioned, tight backs and seats create a plumped-up boxy silhouette, which seems to float above the floor on short tapered feet. Eight pieces offer nearly limitless arrangement possibilities. Among them is an over-scaled ottoman that can hug any piece to extend the configuration. Others are a right- and left-chaise, a right- and left-arm chair, an armless section, an armless loveseat and an armless chaise.
