Airbags and SumoSprings are types of air springs. The main difference between an airbag and SumoSprings is how the air is captured/controlled. With a traditional air bag, a compressor with hoses and valves is used to fill up the balloon inside of the airbag. This requires maintenance so the air bag does not crack and/or leak. The air inside of SumoSprings is captured in millions of air pockets inside the micro-cellular urethane material. You could drill a hole through SumoSprings and they would still work.
