Twenty-six inches square with the padded top at 17 inches, matched to the seat height of the lounge pieces around it. Guests pull it up to a club chair for full-stretch comfort, or use it as extra seating when a group swells past what the layout planned for. Ash Grey aluminum base, top upholstered to order in any fabric on the contract list. Eighteen pounds. Swim clubs, rooftop lounges and boutique courtyards keep several spare for exactly that reason.
