Sierra MX8

Our recently introduced Sierra MX8 offers all of the adjustability of our Sierra ABTS Electric seat in a non-ABTS, mechanical version. 

The Sierra MX8 offers mechanical four-way height, fore-aft, and back recline adjustments to meet a wide range of individual driver or crew seating-comfort requirements.  The Sierra MX8 also features the same shock-isolating, serpentine spring platform found on other Sierra models.

 Available in non-ABTS models only.
