This is our most comfortable seat style yet and it is a 17" wide and 16 1/2" long"Antique Tan Leather Spring Solo Tractor Seat. 100% USA Made! This seat will add a really cool old vintage look to your bike. We start with 1/8" steel pan built in our shop. The pan is very thick, rigid, and sturdy. The pan has a kick up in the back to hold you on the seat. The seat is ergonomically correct to provide a comfortable ride. Next we lay up 1/2" and shape high density urethane closed cell foam on to the pan, to give good support and comfort. Then the foam is covered with high quality top grain leather. Lastly, it is sewn together with heavy duty nylon thread, similar to the way a shoe sole is sewn onto the upper. The qualities of this leather are long life, and durability. The shape and profile of the seat is designed to sit low, to give a slim profile.
