The deliberately simple structure of this visitor chair is defined by a one-piece shell mounted on either a four-legged or cantilevered frame as desired. The flexibility of the shell, the adaptable membrane and the padding all make the chair very comfortable to sit on. The se:flex can optionally be configured with or without armrests. Both frame options can be stacked up to five chairs high. Thanks to its soft and pared-back lines, the chair looks good in many different work settings.
