Both chairs in this bistro set arrive fully assembled and collapse to 3.5 in thick, so a balcony can hold seating for two and still have room to walk through the rest of the week. A locking device holds each chair open in use and releases for folding. The breathable fabric seats stay cool against skin on hot days and dry quickly after rain rather than holding damp, while a metal frame carries up to 330 lb per chair and 135 lb on the 24-in table. The rippled tempered glass top takes a patio umbrella through a 1.57-in hole; the umbrella and its weighted base are sold separately.
