These are super comfortable!  Inflate them just a little for best results.  I have owned several and they fold and transport easily, even in a hip pocket. The downside is the valve which is like a beach balls and becomes very difficult to remove and adjust the amount of air.  The small strap attaching the plug to the valve is what breaks over time.  To fill once and continue to use it this wouldn't be a problem,  but to travel where you need to fill and deflate it's difficult to adjust to the optimum amount of air.<br />I now use mostly Therm-a-rest cushions of which there are many sizes and styles and they have screw valves which are much easier to use!  The Therm-a-rests are also very comfortable but are not as portable as this cushion.  When I sit - car, plane, or computer I always use one or the other of these to avoid a sore butt.<br /><br />.
