Designed by Stanley Felderman and Nancy Keatinge, Collaborate is a new collection of lounge and guest seating for both commercial and residential applications. One of the newest additions to the Haworth Collection, the arm of Haworth that includes Castelli, and distributes Cappellini, Cassina, and Poltrona Frau, the chairs feature a roomy profile (even the slimmer guest chair) to accommodate a variety of seating styles, as well as a 180-degree, self-returning swivel. •
