Nice and narrow with a substantial kick in the back, the Slimline seats are perfect for small chops. The pan is stamped from heavy gauge high-tensile steel and features ribs and indents for added rigidity and stiffness. The stainless steel carriage bolts slide in the slotted holes on the bottom of the pan to match almost any mounting brackets. The entire seat pan is black electroplated for beauty and weatherproofing. The foam inside our upholstered solo seats is custom-molded, medium-density polyurethane padding — not a chunk of old carpet padding. Your butt will know the difference. The cover is made from black vinyl.
