BPA free and Eco Friendly Good for sit ups, crunches, It was easy to pump up with the handheld pump provided. It cane with an extra plug and even better, a little plastic tool you can wedge under the plug to easily pull it out.Good for any basic workout area, and my son likes to use it as a chair to watch TV.
