Ahhhhh
Well I’m back on here to buy two more Wondergel cushions; that should tell you something right there about them!<br />I drive a school bus on very rough rural roads, and this cushion has saved me. Absorbs the shock and bumps tremendously. Purchasing one for my suv and one for my nephew who drives a truck. FYI ; you do need to move them out of direct sunlight when not in use, but it is so worth the hassle.
