The megapopular chair has received sitting ovations by music programs nationwide for accommodating the unique needs of the performance environment. A contoured polypropylene seat combines with a strong 0.87", 16-gauge square tubing frame and 14-gauge rear seat brace along with polyethylene floor glides to prevent scratching. This unit is designed with a band-pitch style seat-to-backrest angle of 97, which allows musicians to perform with optimal breathing posture. Four bumpers protect the powder-coated paint finish when stacking. Stacks up to 18 chairs high on the DY-82 dolly (sold separately).
