Hi Peggy, There are substantial differences, but they boil down to construction and application. Our Commercial inflatables are built exclusively with commercial-grade vinyl. They are about 3 times heavier than Home-Use inflatables for the same size inflatable, and many models are substantially larger in scale than our largest Home-Use inflatables. For example, our largest Home-Use bouncer is about 12x12x7, while we make commercial castles up to 20x20x10. That's 144 square feet vs 400 square feet, and about 50lbs vs 350 lbs for the inflatable. Commercial inflatables are designed for businesses and institutions such as rental companies, schools, churches, etc. and are engineered and certified specifically for these applications. Home-Use inflatables are constructed with commercial-grade vinyl on the Slide, Bounce and Climbing surfaces, and a lighter-weight polyester oxford for other components such as sides, pillars, bottoms, etc. This makes them lighter, less expensive and easier to handle. Home-Use Inflatables are designed for family and personal use. Below are some examples of the type of inflatable for various applications: Application / Recommendation Homeowner, Parent, Etc (Home Inflatables) Day Care (Typically Commercial Inflatables) Church (Commercial Inflatable) School (Commercial Inflatable) Municipality (Commercial Inflatable) Summer Camp (Typically Commercial Inflatables) Neighborhood Collective (Either Depending on Group) Karate Studio, Dance Studio, Etc (Typically Commercial Inflatables) Super-Rich Guy who likes heavy Lifting (Commercial Inflatable) NFL Linebacker (Commercial Inflatable) Indoor Bounce Facility (Exclusively Commercial Inflatables) Clown, Entertainer, Etc (Commercial Inflatable) Inflatable Rental Company (Exclusively Commercial Inflatables) Party Rental Company (Exclusively Commercial Inflatables) Event Planner (Commercial Inflatable) Hope this helps.
