Truck Driver on an off road.
I work heavy highway construction driving a water truck off road on very rough dirt roads. This purple product is a game changer on the impact forces to my lower back. It's like having an additional air ride seat added to the air ride seat I already have in my big truck. The side to side forces we truck drivers take in the seat is what us truck drivers really get hit with a lot and with this purple product it does absorb them extremely well. I weigh 256lbs and not once have i bottomed this out and I'm talking about taking  hits so bad while driving at low speeds if I wasn't in my seat belt I would hit the ceiling in my truck or get thrown out of it. I highly recommend this product. I bought the 2.5 inch thick one. Very impressed.
