I would highly recommend. The inflatables were amazing-looked practically new! The staff was on-time and professional. All my guests were commenting on the quality of the inflatables. Easy and helpful-I will definitely be using again!!!

Just got off phone with this company. I wanted information on renting a bounce house for my kids birthday party. I guess I annoyed the person with too many questions. I have never rented a bounce house before so I needed information. He sounded like he was annoyed that I had questions. I guess I will using another company.

Again, I understand customer service. Yes, you were sold out on the weekend that I wanted but I told the person that I was willing to change weekends.I was willing to go the next Sunday available, which you DID have available. Maybe you didn't review all the facts. The person just kept saying to go to the website to look at information. He DID NOT want to take the time to explain the bounce houses to me. That is why I gave 1 star. I actually called another company that was more than willing to answer my questions and booked them for the following weekend.

The Big Bounce Theory has the best selection of activities and inflatables. They are extremely easy to work with and went out of their way to make my son's party a success, even given rainy and unpredictable weather forecasts. They are friendly, professional and enthusiastic. I strongly recommend them!!

Big Bounce Theory was amazing to work with for our school carnival! They had so many choices and helped us pick the perfect items for the kids. They arrived on time and were fantastic on site the day of the event. The kids had an absolute blast on the different activities. Highly recommend using them for your next event!

We rented a bounce house from thebigbouncetheory.com this weekend for my cousins 3rd birthday party. These guys are awesome, they came early and sent up the Mickey Mouse combo bouncer so the kids got some extra time to jump in the morning. The bounce house was new and cleaned as described and their staff was very accommodating. We had a great experience with this company and would highly recommend anyone looking to rent a bounce house on Long Island!

These guys are the best! If you need a bounce slide look no other place than the big bounce theory! We rented the giant slide that goes into the pool and it was so much fun, not only for the kids but for the adults too! The reservation process was super easy. David and Wes showed up on time, set it up with ease, moved the giant bench that was in the way, was polite, showed us how to use everything, and was a delight to be around. They were helpful and made it quick and painless. We will definitely look forward to renting again next summer when they get the bigger slide! Thanks guys!

We had my daughter's 10th birthday party at our home in Nassau County yesterday. We rented a bounce house and the Radical Run from Big Bounce Theory, as well as some tables. What a wonderful company to work with! Abe (the owner) was a pleasure to work with and helped me figure out what I could fit on my property after asking for some measurements and photos. He even took the time to go on Google Maps to check things out. The Radical Run was such a big hit! Is is an obstacle course but you enter and exit from the same side (it loops around) and it ends in a big slide. Most obstacle courses

Oh my god! I cannot even begin to describe how amazing my party was! Turning 50 is momentous and everything this company provided exceeded my expectations. The games were fantastic. Even though they were games from "my day" they were in excellent condition. They got use throughout the entire party. The photo booth was top notch with tons of fun props and a friendly attendant. The LED lighting created exactly the mood I wanted for my friends and family. The DJ kept everything upbeat. The photographer was great; seeing the pics of people enjoying themselves up on the screens was amazing
