The Postureflex™ SFB banquet chair X916813 gains its unique styling cues by combining traditional silhouetted backs with a center-flex spine to produce a distinctive look. Complement this with a sculpted waterfall seat, and your selection of fabric and finish, and you have a chair that communicates your unique style and décor. This banquet stacker blends the comfort of a center-flex spine and silhouetted back with the ergonomic characteristics of Bertolini’s proprietary Flex-Fit™ polymer seat and a generous portion of our exclusive BLUE commercial grade foam to provide your guests with uncompromising seating comfort. Under its smooth exterior lies the industry’s most durable and sustainable seating structure. We take the industry’s strongest banquet chair frame and add our ZERO Maintenance Flex-Fit™ seat with BosScrew™ technology for rock solid durability. All of this produces a stunning chair that lasts longer and needs replacing less often.
