The driver’s feet maintain control of the pedal because although their body is moving, their knee is at pivot point. “Instead of the whole seat bouncing up and down, our knee-action style suspension seats pivot in the front, so only the back of the seat actually moves,” he explains. Both of these seats are designed to significantly reduce the vertical movement that can occur when maneuvering a large vehicle, Justman says. offers two suspension seats: the Magnum 100 (air suspension) and the Magnum 200 (mechanical suspension). “We’re developing our aftermarket seats that are available direct-to-dealer purchase to help resolve any issues.”ĬVG’s Routemaster 350 Mordura cloth seat features a five-way adjustable seat cushion and adjustable air lumbar support. “We improved the length of the track because we’re listening to the voice of the customer to identify what the problems are in the industry,” Prenatt says. CVG works to ensure the safety of drivers by increasing their track travel from 7 inches to almost 9 inches in some models to allow the seat to move 2 inches closer to the pedal. Height adjustment is important because drivers need to be able to securely reach the pedal. “We provide a product with independent height adjustment so it can fit someone in the 5-foot range, all the way to the 6-foot 7-inch range, and provide maximum comfort for those different heights,” Justman says. That means there is a wide range in drivers’ heights.
