The ultimate utility chair. Stackable, Durabl black powder-coated frame. Three upholstery options - all plastic or upholstered seat only or upholstered seat and back. Non-caster versions use non-marring floor glide which can be upgraded to self-leveling metal glides. Optional ganging clips keep chair arranged and aligned in rows. Choose a model with fixed arms for added comfort or choose a model with casters to facilitate moving.
