Comfort depends mainly on seat choice, fit and adjustment. Trak Racer offers fixed-back, recliner, hybrid Formula/GT, flight and specialty seats, and many cockpits allow the seat, wheel and pedals to be repositioned.
For long sessions, choose a seat that fits your body size and intended seating position, then set the wheel and pedals so you are not over-reaching. Seat specifications and dimensions on the current product page are more useful than a general comfort claim.
