National Seating manufactures a full range of commercial truck seats for fleets across North America. Our medium-duty truck seats are engineered to reduce driver fatigue, alleviate back pain, and decrease downtime across regional, delivery, and vocational duty cycles.
What Are Medium-Duty Truck Seats?
The medium-duty category covers Class 4–7 regional, delivery, and vocational trucks, including box trucks running fixed urban routes. These low-profile seats prioritize durability and ergonomic comfort for frequent cab exits and stop-and-go travel. Standard features across the line include:
✓ Air lumbar support
✓ Cushion extension
✓ Air ride suspension
✓ Multiple color and material options
Air Lumbar Support in Medium-Duty Truck Seats
Air lumbar support reinforces the natural curvature of the lower back and moves with the contours of the body. Prolonged sitting produces discomfort well beyond the lower back, which is why National Seating builds air lumbar into its medium-duty truck seats. The support adjusts to each driver’s preferred firmness, which matters across a mixed driver pool where one seat specification has to serve a range of body types.
Medium-Duty Truck Seats with Cushion Extension
Proper weight distribution is central to sustained body positioning over a full shift. Cushion extension in commercial truck seats allows the front section to extend, adding leg room and closing the gap between the seat pan and the driver’s thighs – support that carries the most value on longer regional runs between stops.
Air Ride Truck Seats
Air ride suspension is standard across the medium-duty line. National Seating uses a suspension system designed for the stop-and-go duty cycles that define regional and delivery work, where repeated compression events accumulate faster than they do over steady highway miles. An air ride truck seat isolates the driver from vibration and road shock, protecting the back and spine across routes with frequent stops, curb transitions, and rough job-site approaches.
Styling Options for Medium-Duty Truck Seats
Fleet specification does not have to mean a single configuration. National Seating offers a variety of seat color configurations and a list of material options:
✓ Vinyl
✓ Forever Cloth
✓ Mordura Cloth
✓ Versa Leather
Choosing Your Medium-Duty Truck Seat
Whether you manage a handful of units or several hundred, National Seating is prepared to assist with your medium-duty truck seat needs. Each seat line carries its own advantages, from suspension covers to seat isolators.
One thing all of our seats have in common is the quality of our products. National Seating is an Original Equipment (OE) supplier, meaning that our medium-duty truck driver seats meet the same standards as seats installed on the factory floor. That consistency holds across an entire fleet, whether units are specified new or retrofitted in service. Our current offering of medium-duty truck seats includes:
Low-profile seat with a hand-pump suspension and 3 inches of vertical travel
Low-profile seat featuring the “chugger-snubber” seat isolator and suspension cover
National Seating also offers a range of adapter plates and truck seat-fitting kits for a secure fit within your vehicle. Our seats are produced in Vonore, Tennessee to help power the drivers who keep America moving.
Sizing Up from a Medium-Duty to a Heavy-Duty Seat
National Seating also manufactures an extensive selection of heavy-duty truck seats for long-haul applications. These seats carry the same benefits – reduced downtime, less driver fatigue, and relief from back pain – while providing 6 inches of vertical movement, rear cushion tilt, and a range of backrest heights.
Heavy-duty truck seats are built for Class 8 trucks and are the right specification for semi-trucks and sleeper applications. Fleets running Class 7 units at the top of the medium-duty range often size up for the additional suspension travel.
