The Body-Solid Utility Stool GST20 is a rock-solid tool for performing seated exercises such as shoulder presses, triceps pullovers, French curls, concentration curls, and wrist curls. It works great in a rack for barbell exercises or on its own with dumbbells. The GST20 is designed to align your body to a perfect seated posture and reduce stress on your back without restricting movement. Both seat pads are mounted to the heavy-duty 2" x 2" and 2" x 3" mainframe, which is constructed from 12-gauge high-tensile strength steel for maximum strength and features an extra-wide base that ensures lateral stability. When it comes to padding, you can't beat BodySolid's extra thick, double-stitched DuraFirmTM upholstery. It's tear resistant and guaranteed to provide a lifetime of comfort and support without ever bottoming out. Whether it is in a home or commercial setting, the GST20 is the best seat in the house!
