The Mac Tools 2-in-1 Seat-Stool Combo, No. CRS350, is a multi-purpose seat with a 2-in-1 function built around a strong professional-grade reinforced steel frame. It is topped with an extra-thick cushion for comfort and a treaded steel plate for added traction while standing on top of the stool. The patent-pending rolling seat rolls smoothly around on top of five 3” oil-resistant, 360-degree rotating casters for easy mobility while keeping all tools at hand in the thick, plastic tool tray.
