The Sierra Defender A350 creates a smooth and safe ride by utilizing a unique shock-isolating system that allows drivers to keep consistent contact with vehicle controls at all times while on bumpy terrain. 

It features a 3.5" (89 mm) of air suspension travel, 3" (76 mm) of height adjustment with 4 locking positions, lever-actuated recline, and a 20" (508 mm) wide seat cushion with multi-density foam. Each pivot point incorporates bronze bushings for rigid, maintenance-free operation. Easily adjust the Defender A350 seat using two separate release handles located at the front of the seat: one for the height adjust and one for the fore/aft adjust.

Include an optional two-point seat belt or cutout in the backrest for a rope bag, depending on your application.
