Our Automobile seat cushion was developed as a way of reducing the physical discomfort, as well as fatigue associated with long term driving. Trauma-Tek™, with Confor®, is able to reduce as much as 90% of the static trauma caused by sitting, as well as the blunt force and vibration trauma generated by the road. Designed to fit most automobiles, trucks, and vans, the ASC-300 is made of 1 1/8" Trauma-Tek™ when measured at it thickest point. It is light weight, only 1 ¼ lbs. It measures 19” long by 17” wide at its widest point.
