Foam. Smooth stitch style upholstery. Rider seat 14.5″ wide, passenger seat 12.5″ wide. If the emphasis is on cruising in comfort, for both rider and passenger, this seat is a strong contender. Maximum touring comfort in a classic style. The Maverick provides great lower back support, a deep bucket for the rider and the tapered mid-section allows you to plant your feet on the ground easier than with most seats for a confident stop.
