Seats Inc. says it developed its Legacy Series with supreme driver comfort and versatility in mind.

The truck-seat series includes the Legacy Silver, with two-way air lumbar support and a standard parallelogram suspension; the Legacy LO with four-way lumbar and an anti-topping/bottoming out low-profile suspension suitable for Class 6-7 trucks; and the Legacy HD, also with four-way lumbar but featuring a heavy-duty wide suspension for extreme applications.

All models have Seats' EVC cushion support system. As opposed to wooden or metal boards or pans, the company explains, the EVC cushion sling provides a trampoline-type material for the foam cushion to rest on.

This significantly reduces road vibration, driver fatigue and tailbone pressure for a more comfortable ride.
