Driver comfort and retention are at the very heart of the Pinnacle’s design. The Pinnacle includes an enhanced EVC cushion comfort System™, D2 Foam Technology™, a fully reclining backrest and the longest armrest in the industry. It excels further, providing an 8-position extendable cushion, 13 degrees (+/-) adjustable rake, and an air lumbar package including both dual lumbars plus side bolsters. All Pinnacle comfort features have been developed utilizing sophisticated pressure mapping equipment minimizing pressure points, expanding adjustability, and maximizing comfort.
